A gang is a group of recurrently associating individuals or close friends with identifiable leadership and internal organization, identifying with or claiming control over territory in a community, and engaging either individually or collectively in violent or other forms of illegal behavior. Gang members are typically "jumped in" or have to prove their loyalty by committing acts such as theft or violence. Although gangs exist internationally, there is a greater level of study and knowledgeable information of gangs specifically in the United States. A member of a gang is called a gangster.
Gangs are prominent in the larger cities and urban areas in the United States, in prisons and jails while many branches of the original gang are present in small towns and suburbs. American gangs originated in New York City and Chicago and the surrounding areas. The gangs competed with one another for various reasons, such as during the prohibition era for control of illegal drinks, and would often beat or even murder an opposing gang member for attempting to sell or distribute illegal liquor on their "turf". This resulted in retaliation and eventually a "war" between the opposing gangs. In current usage, it typically denotes a criminal organization or else a criminal affiliation. In early usage, the word gang referred to a group of workmen. In the United Kingdom, the word is still often used in this sense, but it later underwent pejoration. The word gang often carries a negative connotation; however, within a gang which defines itself in opposition to mainstream norms, members may adopt the phrase as a statement of identity or defiance.
In discussing banditry in Chinese history, Barrington Moore, Jr. suggests that gangsterism as a "form of self-help which victimizes others" may appear in societies which lack strong "forces of law and order"; he characterizes European feudalism as "mainly gangsterism that had become society itself and acquired respectability".
A wide variety of gangs, such as the Order of Assassins, Adam the Leper's gang, Penny Mobs, Indian Thugs, Chinese Triads, Snakehead, Japanese Yakuza, Irish mob, Pancho Villa's Villistas, Dead Rabbits, American Old West outlaw gangs, Bowery Boys, Chasers, the Italian mafia, Jewish mafia, and Russian Mafia crime families have existed for centuries. According to some estimates the Thuggee gangs in India murdered 1 million people between 1740 and 1840.
The 17th century saw London "terrorized by a series of organized gangs", some of them known as the Mims, Hectors, Bugles, and Dead Boys. These gangs often came into conflict with each other. The members dressed "with colored ribbons to distinguish the different factions." Many poor orphans in Victorian London survived by joining pick-pocketing gangs controlled by adult criminals. At the beginning of the 19th century, child criminals in Britain were punished in the same way as adults. They were sent to adult prisons, transported to the various Australian penal colonies, flogged, and sentenced to death for crimes such as petty theft.
In the United States, the history of gangs began on the East Coast in 1783 following the American Revolution. The emergence of the gangs was largely attributed to the vast rural population immigration to the urban areas. The first street-gang in the United States, the 40 Thieves, began around the late 1820s in New York City. In 1850, New York City recorded more than 200 gang wars fought largely by youth gangs. All the major cities of Victorian England in the late 19th century had gangs. Chicago had over 1,000 gangs in the 1920s. These early gangs had reputations for many criminal activities, but in most countries could not profit from drug trafficking prior to drugs being made illegal by laws such as the 1912 International Opium Convention and the 1919 Volstead Act. Gang involvement in drug trafficking increased during the 1970s and 1980s, but some gangs continue to have minimal involvement in the trade.
Current numbers 
In theUnited States in 2007
there were approximately 785,000 active street gang members, according to the National Youth Gang Center. In 2011 the National Gang Intelligence Center of the Federal Bureau of Investigation asserted that "There are approximately 1.4 million active street, prison, and outlaw gang members comprising more than 33,500 gangs in the United States." Approximately 230,000 gang members were in U.S. prisons or jails in 2011.
The newly released Chicago Crime Commission publication, "The Gang Book 2012", conveyed the statistic that Chicago has more gang members than any other city in the United States: 150,000 members. Traditionally Los Angeles County has been considered the Gang Capital of America, with an estimated 120,000 (41,000 in the City) gang members.
Chicago has a higher rate of gang membership per capita than Los Angeles. The state of Illinois has a higher rate of gang membership (8-11 gang members per 1,000 population) than California (5-7 gang members per 1,000 population).
There were at least 30,000 gangs and 800,000 gang members active across the USA in 2007. About 900,000 gang members lived "within local communities across the country," and about 147,000 were in U.S. prisons or jails in 2009. By 1999, Hispanics accounted for 47% of all gang members, Blacks 31%, Whites 13%, and Asians 6%.
Tribal leaders say Native American communities are being overwhelmed by gang violence and drug trafficking. A Dec. 13, 2009 The New York Times article about growing gang violence on the Pine Ridge Indian Reservation estimated that there were 39 gangs with 5,000 members on that reservation alone. Navajo country recently reported 225 gangs in its territory.
The Russian, Chechen, Azerbaijani, Ukrainian, Georgian, Armenian, and other former Soviet organized crime groups or "Bratvas" have many members and associates affiliated with their various sorts of organized crime but a rough number has not been estimated.
Notable examples 
Perhaps the best known criminal gangs are the Italian Cosa Nostra, commonly known as the Mafia. The Napolitan Camorra, the Calabrian 'Ndrangheta and the Apulian Sacra Corona Unita are similar Italian organized gangs.
Other criminal gangs include the Russian Mafia, Mexican and Colombian drug cartels, the Chinese Triads, the Mexican Mafia, the Irish Mob, the Japanese Yakuza, the Jamaican-British Yardies and other crime syndicates.
On a lower level in the criminal gang hierarchy are street gangs in the United States, such as the Sureños, Norteños, Crips, Bloods, Nazi Lowriders, Latin Kings, Vice Lords and Gangster Disciples. Biker gangs (such as the Hells Angels and the Mongols Motorcycle Club) and white power skinhead gangs are also notable.
Types and structure 
Many types of gangs make up the general structure of an organized group.
There are street gangs, which are people with similar backgrounds and motivations. The term “street gang” is commonly used interchangeably with “youth gang,” referring to neighborhood or street-based youth groups that meet “gang” criteria. Miller (1992) defines a street gang as “a self-formed association of peers, united by mutual interests, with identifiable leadership and internal organization, who act collectively or as individuals to achieve specific purposes, including the conduct of illegal activity and control of a particular territory, facility, or enterprise."
Understanding the structure of gangs is a critical skill to defining the types of strategies that are most effective with dealing with them, from the at-risk youth to the gang leaders. Not all individuals who display the outward signs of gang membership are actually involved in criminal activities. An individual's age, physical structure, ability to fight, willingness to use violence, and arrest record are often principal factors in determining where an individual stands in the gang hierarchy; now money derived from criminal activity and ability to provide for the gang also impacts the individual’s status within the gang. The structure of gangs varies depending primarily on size which can range in size from five or ten to several thousand. Many of the larger gangs break up into smaller groups, cliques or sub-sets. The cliques typically bring more territory to a gang as they expand and recruit new members. Most gangs operate informally with leadership falling to whoever takes control; others have distinct leadership and are highly structured, much like a business or corporation.
Matthew O’Deane, Ph.D., has identified five primary steps of gang involvement applicable to the majority of gangs in the world; at risk, associates, members, hardcore members and leaders.
"At Risk” or "Peripheral" 
This group of kids is not considered gang members by law enforcement, but they know gang members and may associate with them on a casual or limited basis, mostly watching and imitating the older gang members. They are getting close to an age where they might decide to join the gang. They may like and admire the gang members in the neighborhood and the gang lifestyle, but do not participate in the gang’s criminal activity. This group is generally between 7 and 9 years old.
“Associates” or “Affiliates” 
These kids associate with gang members on a regular basis and tend to consider gang life normal and acceptable. They find certain things in common with gang members and are seriously thinking about joining the gang. Some associates consider themselves members, even if they have not yet been formally initiated. This person is commonly called a “Wanna Be”, “Pee Wee”, or “Baby Gangster” ; many may claim to back up the gang if confronted by law enforcement. They may act, walk, talk, and dress like gang members and will tend to socialize with them. These associates are sometimes used by older gang members to do specific tasks, such as serving as lookouts, runners, or for writing graffiti. This group typically lacks direction and may drift in and out of the gang depending on the current activities of the gang. This person is generally between the ages of 9 and 13, but can range from 7 to 18 years old in some cases. It is often difficult to distinguish an associate from a member by looking at them. The difference is in their commitment to the gang.
“Gang Member” 
This person associates almost exclusively with other gang members, to the exclusion of family and former friends. They have shifted their loyalty from their family to their gang. This person participates in gang crimes and most of the gang’s activities. They make up the bulk of a gang’s membership and are held responsible for protection of the gang's turf and fellow gang members. This person is generally between the ages of 14 and 20 years old, but, in some extreme cases, can range from 11 to 40 years old. The gang member has a much more significant attachment to the gang mentality, or code, when compared to an associate. Nowadays there are also "wannabes" who are usually young children who want to be in a gang and act like gang members at various young ages.
“Hard Core Gang Member” 
This gang member has become totally committed to the gang and gang lifestyle, commonly referred to as an “OG” or Original Gangster or “Veterano”. This usage has changed from its original meaning, which indicated a founding member of a gang or one who was active in the 1960s or 1970s.
They usually reject any value system other than that of his/her gang and their life revolves around the gang. This member typically has been arrested and been through the justice system. This person will commit any crime or act of violence to further the goals and objectives of the gang. This person is usually in his/her late teens or early 20’s extending into their 30’s in some cases.
“Gang Leader” 
These members are the upper echelons of the gang’s command. This gang member is probably the oldest in the posse and likely has the smallest criminal record and they often have the power to direct the gang’s activity, whether they are involved or not. In many jurisdictions, this person is likely a prison gang member calling the shots from within the prison system or is on parole. Often, they distance themselves from the street gang activities and make attempts to appear legitimate, possibly operating a business that they run as fronts for the gang’s drug dealing or other illegal operations.
Prison gangs are groups in a prison or correctional institution for mutual protection and advancement. Prison gangs often have several "affiliates" or "chapters" in different state prison systems that branch out due to the movement or transfer of their members. The 2005 study neither War nor Peace: International Comparisons of Children and Youth in Organized Armed Violence studied ten cities worldwide and found that in eight of them, "street gangs had strong links to prison gangs". According to criminal justice professor John Hagedorn, many of the biggest gangs from Chicago originated from prisons. From the St. Charles Illinois Youth Center originated the Conservative Vice Lords and Blackstone Rangers. Although the majority of gang leaders from Chicago are now incarcerated, most of those leaders continue to manage their gangs from within prison.
Criminal gangs may function both inside and outside of prison, such as the Nuestra Familia, Mexican Mafia, Folk Nation, and the Brazilian PCC. During the 1970s, prison gangs in Cape Town, South Africa began recruiting street gang members from outside and helped increase associations between prison and street gangs. In the USA, prison gang Aryan Brotherhood is in organized crime outside prison.
Who joins and why 
The numerous push factors experienced by at-risk individuals vary situationally however follow a common theme for the desire of power, respect, money and protection. These factors are very influential in the luring process and largely contribute to the reasons why individuals join gangs. These factors are particularly more attractive and influential on at-risk youth. Many times individuals are experiencing low levels of these various factors in their own lives, and feel that joining a gang is the only way to obtain status and success. Unfortunately, a common sentiment is "if you can't beat 'em, join 'em". These at-risk individuals feel ostracized from the community and are experiencing a lack of social support. Upon joining a gang, they instantly gain a feeling of belonging and identity; they are surrounded with individuals whom they can relate to. They have generally grown up in the same area as each other and can bond over similar needs. In some areas, joining a gang is an integrated part of the growing up process.
Typical activities 
The United Nations estimates that gangs make most of their money through the drugs trade, they are thought to be worth $352bn in total. The United States Department of Justice estimates there are approximately 30,000 gangs, with 760,000 members, impacting 2,500 communities across the United States.
Gangs are involved in all areas of street-crime activities like extortion, drug trafficking, both in and outside the prison system and theft. Gangs also victimize individuals by robbery and kidnapping. Cocaine is the primary drug of distribution by gangs in America, which have used the cities Chicago, Cape Town, and Rio de Janeiro to transport drugs internationally. Brazilian urbanization has driven the drug trade to the favelas of Rio. Often, gangs hire "lookouts" to warn members of upcoming law enforcement. The dense environments of favelas in Rio and public housing projects in Chicago have helped gang members hide from police easily.
Street gangs take over territory or "turf" in a particular city and are often involved in "providing protection", often a thin cover for extortion, as the "protection" is usually from the gang itself, or in other criminal activity. Many gangs use fronts to demonstrate influence and gain revenue in a particular area.
Gang violence 
Gang violence refers to mostly those illegal and non-political acts of violence perpetrated by gangs against innocent people, property, or other gangs. Throughout history, such acts have been committed by gangs at all levels of organization. Nearly every major city was ravaged by gang violence at some point in its history. Modern gangs introduced new acts of violence, which may also function as a rite of passage for new gang members.
58 percent of L.A.’s murders were gang-related in 2006. Reports of gang-related homicides are concentrated mostly in the largest cities in the United States, where there are long-standing and persistent gang problems and a greater number of documented gang members—most of whom are identified by law enforcement.
There have been reports of racially motivated attacks against African Americans. Members of the Azusa 13 gang, associated with the Mexican Mafia, were indicted in 2011 for harassing and intimidating black people in Southern California.
Gang War 
|This section requires expansion. (March 2013)|
||This article's tone or style may not reflect the encyclopedic tone used on Wikipedia. (April 2013)|
A Gang War is a type of small war that occurs when two gangs end up in a feud over territory.
Usually, gangs have gained the most control in poorer, urban communities and the Third World in response to unemployment and other services. Social disorganization, the disintegration of societal institutions such as family, school, and the public safety net enable groups of peers to form gangs. According to surveys conducted internationally by the World Bank for their World Development Report 2011, by far the most common reason people suggest as a motive for joining gangs is unemployment.
Ethnic solidarity is a common factor in gangs. Black and Hispanic gangs formed during the 1960s in the USA often adapted nationalist rhetoric. Both majority and minority races in society have established gangs in the name of identity: the Igbo gang Bakassi Boys in Nigeria defend the majority Igbo group violently and through terror, and in the United States, whites who feel threatened by minority rights have formed their own groups, such as the Ku Klux Klan. Responding to an increasing black and Hispanic migration, a white gang called Gaylords formed in Chicago.

Most gang members have identifying characteristics unique to their specific clique or gang. The Bloods, for instance, wear red bandanas, the Crips blue, allowing these gangs to "represent" their affiliation. Any disrespect of a gang member's color by an unaffiliated individual is regarded as grounds for violent retaliation, often by multiple members of the offended gang. Tattoos are also common identifiers, such as an '18' above the eyebrow to identify an 18th Street (gang) member. Tattoos help a gang member gain respect within their group, and mark them as members for life. They can be burned on as well as inked. Some gangs make use of more than one identifier, like the Nortenos, who wear red bandanas and have '14,' 'XIV,' 'x4,' and 'Norte' tattoos. Also, many male gang members wear earrings or other types of body jewelry, or simply have pierced ears to depict gang membership, unlike females, who usually wear jewelry for appearance.
Gangs often establish distinctive, characteristic identifiers including graffiti tags colors, hand signals, clothing (for example, the gangsta rap-type hoodies), jewelry, hair styles, fingernails, slogans, signs (such as the noose and the burning cross as the symbols of the Klan), flags secret greetings, slurs, or code words and other group-specific symbols associated with the gang's common beliefs, rituals, and mythologies to define and differentiate themselves from other groups and gangs.
As an alternative language, hand-signals, symbols, and slurs in speech, graffiti, print, music, or other mediums communicate specific informational cues used to threaten, disparage, taunt, harass, intimidate, alarm, influence, or exact specific responses including obedience, submission, fear, or terror. One study focused on terrorism and symbols states: "… Symbolism is important because it plays a part in impelling the terrorist to act and then in defining the targets of their actions." Displaying a gang sign, such as the noose, as a symbolic act can be construed as "… a threat to commit violence communicated with the intent to terrorize another, to cause evacuation of a building, or to cause serious public inconvenience, in reckless disregard of the risk of causing such terror or inconvenience…an offense against property or involving danger to another person that may include but is not limited to recklessly endangering another person, harassment, stalking, ethnic intimidation, and criminal mischief."
The Internet is one of the most significant mediums used by gangs to communicate in terms of the size of the audience they can reach with minimal effort and reduced risk. The Internet provides a forum for recruitment activities, typically provoking rival gangs through derogatory postings, and to glorify their gang and themselves. Gangs are using the Internet to communicate with each other, facilitate criminal activity, spread their message and culture around the nation. As Internet pages like MySpace, YouTube, Twitter, AIM, and Facebook become more popular, law enforcement works to understand how to conduct investigations related to gang activity in an online environment. In most cases the police can and will get the information they need, however this requires police officers and federal agents to make formal legal requests for information in a timely manner, which typically requires a search warrant or subpoena to compel the service providers to supply the needed information. A grand jury subpoena or administrative subpoena, court order, search warrant; or user consent is needed to get this information pursuant to the Electronic Communication Privacy Act, Title 18 U.S.C. § 2701, et seq. (ECPA). Just about every gang member has personal web page or some type of social networking internet account or chat room where they post photos and videos and talk openly about their gang exploits. The majority of the service providers that gang members use are free social networking sites that allow users to create their own profile pages, which can include lists of their favorite musicians, books and movies, photos of themselves and friends, and links to related web pages. Many of these services also permit users to send and receive private messages and talk in private chat rooms. Many times a police officer may stumble upon one of these pages, or an informant can get you into the local gang page, providing you a name and password to use to get in and explore, other times you do not have that option and will have to formally request the needed information. Most service providers have four basic types of information about its users that may be relevant to a criminal investigation; 1) basic identity/subscriber information supplied by the user in creating the account; 2) IP log-in information; 3) files stored in a user’s profile (such as “about me” information or lists of friends); and 4) user sent and received message content. It is important to know the law, and understand what exactly we can get service providers to do and what their capabilities are. It is also important to understand how gang members use the Internet and how we as the police can use their desire to be recognized and respected in their sub-culture against them.
Gang membership in the US military 
Gang members in uniform use their military knowledge, skills and weapons to commit and facilitate various crimes. As of April 2011, the NGIC has identified members of at least 53 gangs whose members have served in or are affiliated with US military.
In 2006, Scott Barfield, a Defense Department investigator, said there is an online network of gangs and extremists: "They're communicating with each other about weapons, about recruiting, about keeping their identities secret, about organizing within the military."
A 2006 Sun-Times article reports that gangs encourage members to enter the military to learn urban warfare techniques to teach other gang members. A January 2007 article in the Chicago Sun-Times reported that gang members in the military are involved in the theft and sale of military weapons, ammunition, and equipment, including body armor. The Sun-Times began investigating the gang activity in the military after receiving photos of gang graffiti showing up in Iraq.
The FBI’s 2007 report on gang membership in the military states that the military's recruit screening process is ineffective, allows gang members/extremists to enter the military, and lists at least eight instances in the last three years in which gang members have obtained military weapons for their illegal enterprises. "Gang Activity in the U.S. Armed Forces Increasing", dated January 12, 2007, states that street gangs including the Bloods, Crips, Black Disciples, Gangster Disciples, Hells Angels, Latin Kings, The 18th Street Gang, Mara Salvatrucha (MS-13), Mexican Mafia, Norteños, Sureños, and Vice Lords have been documented on military installations both domestic and international although recruiting gang members violates military regulations.
