Universal background check
Proposals for universal background checks would require almost all firearms transactions in the United States to be recorded and go through the National Instant Criminal Background Check System (NICS), closing what is sometimes called the private sale exemption. Universal background checks are not required by U.S. federal law, but at least 22 states and the District of Columbia currently require background checks for at least some private sales of firearms.
Federal law requires background checks (through the National Instant Criminal Background Check System) only for guns sold through licensed firearm dealers, which account for 78% of all gun sales in the United States. This figure was published in a 2017 study by the Annals of Internal Medicine which, using a 2015 survey, found that 22% of recent gun transfers (purchased and nonpurchased) were completed without a background check. The authors noted that while this number was less than in years past, it nonetheless indicates that millions of American adults are able to obtain firearms without background checks. The current federal law allows people not "engaged in the business" of selling firearms to sell firearms without a license or records. A 2008 report from the Coalition to Stop Gun Violence (CSGV) stated that the National Instant Criminal Background Check System had prevented over 1.4 million felons and other prohibited persons from purchasing firearms in the years between 1994-2005. According to the CSGV, the law also has a prohibitive effect, that deters illegal purchases.
In November 1998, President Bill Clinton directed the U.S. Secretary of the Treasury and the U.S. Attorney General (A.G.) to provide recommendations concerning the fact that 25 percent or more of sellers at gun shows are not required to run background checks on potential buyers. This was called the gun show loophole.:3,12:27 Two months later, Gun Shows: Brady Checks and Crime Gun Traces was released. The Secretary and the A.G. made seven recommendations, including expanding the definition of "gun show," and reviewing the definition of "engaged in the business".
After the Columbine High School massacre in April 1999, gun shows and background checks became a focus of national debate. In May, the executive vice president of the National Rifle Association (NRA) told the House Judiciary Subcommittee on Crime, "We think it is reasonable to provide mandatory, instant criminal background checks for every sale at every gun show.":118 Those concerned about the shows believed they were a source of illegally trafficked firearms.[nb 1] Efforts to reverse a key feature of the Firearm Owners Protection Act (FOPA) by requiring criminal background checks and purchase records on private sales at gun shows, which had become prolific in the U.S. since the law's passage in 1986, were unsuccessful.
Private sale exemption
In the August 5, 2010, issue of The New England Journal of Medicine, researchers Garen J. Wintemute, Anthony A. Braga, and David M. Kennedy, wrote that gun shows account for only a fraction of all U.S. gun sales and that a more effective strategy would be to make all private-party gun sales go through the screening and record-keeping processes that FFL dealers are required to do. Their report concluded:
Drawbacks with respect to expense and inconvenience notwithstanding, 83% of self-reported gun owners and 87% of the general population endorsed regulation for all private-party gun sales in a 2008 poll that was conducted for the advocacy organization Mayors Against Illegal Guns. Gun owners gave stronger support to this all-inclusive approach than to a gun-show-only proposal in a 2009 poll conducted for the same organization. Either proposal would face tough sledding on Capitol Hill. It would therefore seem preferable to move forward with the version that is most likely to reduce the rates of firearm-related violence.
Following the December 14, 2012 Sandy Hook Elementary School massacre, there were numerous calls for universal background checks to close what is now referred to as the "private sale loophole." In an essay published in 2013, Wintemute said that comprehensive background checks that included private sales would result in a simple, fair framework for retail firearms commerce.:103 In February 2014, researchers at the Johns Hopkins Center for Gun Policy and Research reported that after the 2007 repeal in Missouri of a long-standing law that required all handgun buyers to pass a background check there was a 23 percent increase in firearms homicides.
A 2012 study published in the journal Injury Prevention found that nearly 80% of all firearms used for criminal purposes are obtained through transfers from unlicensed dealers, which are not required to conduct background checks in a majority of states due to the private sale exemption.
In 2017, a study by researchers from Northeastern University and the Harvard School of Public Health showed that 22% of American gun owners who had obtained a gun in the previous two years did not undergo a background check before doing so.
Universal background checks enjoy high levels of public support; a 2016 representative survey found 86% of registered voters in the United States supported the measure. Five national polls conducted in 2015 show high levels of support for "expanded background checks for gun purchases," with rates varying (93% and 89% support in two Quinnipiac University surveys, 92% support in a CBS/New York Times survey, 86% support in a Gallup survey, 85% support in a Pew Research Center survey). A 2015 survey found that more than 90% of Americans supported universal background checks, and that, on average, Americans thought they would be more effective than any other gun policy. There is evidence that many Americans incorrectly think that universal background checks are required by federal law; a 2016 survey found that 41% of Americans believed this to be the case. The same survey found that 77% of Americans supported universal background checks, while only 53% supported stricter gun laws. Based on this data, the authors concluded that "this difference might be attributable to poor awareness of the limitations of existing laws."
In 2015, large majorities of American adults, both Republicans (79%) and Democrats (88%), supported background checks for private sales and at gun shows, according to a Pew Research Center survey. In 2017, strong majorities of American adults, both gun owners (77%) and non-gun owners (87%), supported background checks for private sales and at gun shows, according to a Pew Research Center survey with an error attributable to sampling of +/- 2.8% at the 95% level of confidence. In 2018, after the Stoneman Douglas High School shooting in Parkland, Florida, nearly all Americans supported universal background checks. 88% of registered voters supported universal background checks, according to a Politico/Morning Consult poll with a margin of error +/- 2%. 94% of American voters supported universal background checks, according to a Quinnipiac University Polling Institute poll with a margin of error of +/- 3.4%.
A July 2019 poll by NPR found that 89% of respondents supported background checks for all gun purchases at gun shows or other private sales. An overwhelming majority of Republicans (84%) and Democrats (96%) indicated their support, suggesting there is bipartisan popular consensus on the broad topic in the public.
Gun rights groups such as the National Rifle Association and National Shooting Sports Foundation oppose universal background check proposals. Opponents of universal background checks argue that existing gun laws are sufficient; that the government does not prosecute enough of the attempted ineligible buyers who are turned away by the current system; that background checks are an invasion of privacy; and that "transfer" might be defined too broadly. Opponents also maintain that universal background checks would not stop crime and assert that the only way to properly enforce a universal system would be to require a registration database. Gun-rights advocate and author John Lott argues that universal background checks prevent poorer Americans from acquiring guns. Lott said that, as of December 2015, background checks added an effective cost of $80 (New York), $60 (Washington state), or $200 (Washington, D.C.) to transferring a firearm. Lott argues that universal background checks are an effective tax on guns and can prevent less affluent Americans from purchasing them, and that this disproportionately affects poor minorities who live in high-crime urban areas.
Universal background check laws were associated with a 14.9% reduction in overall homicides, according to a 2019 study by medical researchers including Michael Siegel of the Boston University School of Public Health and David Hemenway of the Harvard T.H. Chan School of Public Health published by the Journal of General Internal Medicine. The study authors wrote that "further research is necessary to determine whether these associations are causal ones".
An October 2018 study conducted by the Violence Prevention Research Program (VPRP) at UC Davis and the Center for Gun Policy and Research at Johns Hopkins Bloomberg School of Public Health found no change in firearm homicide or suicide rates in the ten years following California's 1991 implementation of comprehensive background checks. The study's control group used firearm and non-firearm mortality data for 32 states that did not implement major firearm policies during the period from 1981-2000. In the study period, firearm suicide rates were 10.9 percent lower in California but a similar decrease in non-firearm suicide was also observed. The study found no net difference between firearm-related homicide rates before and during the study period. The study authors identified a number of possible reasons for the null finding, including inadequate reporting of criminal records or other disqualifying information to background-check databases (especially pre-2000); a failure by sellers to conduct the background check as required by law; and the small number of persons affected by the California law.
Another study by the VPRP found that comprehensive background check policies led to increased background checks in Delaware, but not in Colorado or Washington. Non-compliance with the policy may be attributable to the lack of an increase in the latter two states.
A study published in July 2018 found no association between firearm homicide and suicide rates and the repeal of comprehensive background check laws in two states. The study compared rates from synthetic control groups to rates in Indiana from 1981 to 2008 and in Tennessee from 1994 to 2008. Rates from the two states' study periods were within the range of natural variability. The study also concluded that in order to understand whether comprehensive background checks generally reduce firearm deaths, more evidence from other states is needed.
A study published in June 2018 in the Journal of Urban Health by authors affiliated with the Violence Prevention Research Program (VPRP) at UC Davis and the Center for Gun Policy and Research at Johns Hopkins Bloomberg School of Public Health found comprehensive background check (CBC) laws not tied to a permit-to-purchase law were associated with an increase in firearm homicide rates but not non-firearm homicide rates. The authors of the study noted, however, that they have "identified no plausible theory to explain how requiring a prospective firearm purchaser to undergo a background check would result in increased homicide rates." In attempting to explain the unexpected results, the researchers proposed an endogenous relationship such that states passing the CBC-only laws were doing so in response to already rising firearm homicide rates.
A 2016 study published in The Lancet attempted to measure the impact that 25 different state laws had on overall firearm-related mortality, and it found that universal background checks had the strongest overall impact. Additionally, the researchers' projection of a federally implemented universal background check policy predicted that national firearm mortality could drop from 10.35 deaths per 100,000 people to 4.46 deaths per 100,000 people. A 2015 study published in the American Journal of Public Health found that a Connecticut law (enacted in 1995) requiring handgun buyers to undergo a background check (in order to obtain a required permit) "was associated with a 40 percent decline in gun homicides and a 15 percent drop in suicides" during the law's first ten years in effect. A 2014 study published in the Journal of Urban Health found that the 2007 repeal of a "permit-to-purchase" handgun law in Missouri (including the repeal of a background-check requirement) was associated with a 23% increase in the firearm homicide rate and a 15% increase in the murder rate, translating "to increases of between 55 and 63 homicides per year in Missouri." The study controlled for other variables that might affect homicides, including "changes in rates of unemployment, poverty, incarceration, burglary, law enforcement officers per capita, and the presence of four other types of state laws." A 2013 study published in the JAMA Internal Medicine analyzed various types of firearm legislation across the U.S. from 2007-2010 and firearm-related deaths across all 50 states, and concluded that stronger background checks were associated with lower overall firearm fatality rates.
In a survey published by the New York Times in January 2017, a panel of 32 scholars of criminology, public health, and law rated universal background checks as the most effective policy to prevent gun deaths, ranking it #1 of 29 possible gun-related policies (7.3 on a 10-point effectiveness scale). In a subsequent expert survey published in October 2017 on policies to curb mass shooting deaths specifically, the expert panel ranked universal checks for gun buyers and universal checks for ammunition buyers as 6.6 and 6.5 (on a 10-point effectiveness scale), respectively, ranking them as the fifth- and sixth-most effective of 20 gun-policy proposals.
A survey by Arthur Berg, Gary Mauser, and John Lott, published in the winter 2019-2020 edition of the Cato Institute quarterly Regulation, asked respondents (38 criminologists, 32 economists, and 50 public health researchers who had published an empirical study on firearms in a peer-reviewed journal) to rank the effects of 33 firearms policies (20 policies in the New York Times in 2017, plus 8 additional policies that would loosen gun regulation, and 5 additional restrictive policies) on reducing murder rates and mass shootings. (Berg, Mauser, and Lott asked about "murder rates" rather than gun homicides because they made the assumption that stricter gun laws would not affect the homicide rate.) Respondents ranked universal background checks 13th and 14th for reducing the murder rate and reducing mass shootings, respectively. Public health researchers were substantially likelier than economists and criminologists to rate universal background checks as effective.
Implications for mental health counseling
Universal background check laws, which require that a background check be conducted before any gun transfer, may apply to temporary removals of guns from the home of suicidal individuals. Some clinicians have reported that these laws have created confusion about whether a gun transfer would be legal, and therefore made it more difficult for them to counsel their patients.

In Maine, a 2016 referendum to require background checks on private sales failed after a closely fought campaign, with "yes" gaining 48.2% of the vote and "no" gaining 52.8% of the vote. In 2014, a referendum in Washington state to require background checks on private sales (Initiative Measure No. 594) passed, with "yes" gaining 59.3% of the vote and "no" gaining 40.7% of the vote.
