Mr. Big (police procedure)
Mr. Big (also known as the Canadian technique) is a covert investigation technique used by undercover police investigators in some parts of Canada and Australia to gather confessions for prosecution. In this method, police officers gain the confidence of the suspect, and then enlist the suspect's help in an escalating series of fictional crimes. Once the suspect has become involved in the fake crimes, the police persuade the suspect to divulge what knowledge they may have of the crime being investigated.
In July 2014 the Supreme Court of Canada ruled that confessions made in Mr. Big operations were "presumptively inadmissible" as evidence in a criminal trial. Within a few months, some charges had been dropped as a result of the ruling.

The technique was developed by the Royal Canadian Mounted Police (‘RCMP’) in Vancouver, British Columbia in the early 1990s for cold case homicide investigations. In British Columbia, the technique has been used over 180 times, and, in 80% of the cases, it resulted in either a confession or the elimination of the suspect from suspicion. Since 1990, police in Victoria Australia have also used the technique on over 20 cases, and have successfully obtained murder confessions in several. In Australia, police have applied to the courts, unsuccessfully, to suppress the publication of the details of these tactics. It has also been used in New Zealand.
While the details of the technique vary from case to case, the method is for an undercover police unit to pose as members of a fictitious gang into which the suspect is inducted. The suspect is invited to participate in a series of escalating criminal activities (all of which are faked by the police), including robberies, control of prostitution, and standing guard during gang's activities. In addition, the "gang members" build a personal relationship with the suspect, through drinking together and other social activities. The goal is to win the confidence of the suspect. Eventually, the suspect is told that the police have a renewed interest in the original crime, and that the suspect needs to give the gang further details. The suspect is told that the boss (the so-called "Mr. Big") may have the ability to influence that police investigation, but only if the person reveals what, if any, knowledge they have of the crime being investigated. They are also told that if they aren't completely truthful about their knowledge the gang may not be willing to continue to work with him, as he may be a liability.
Defense lawyers and criminal specialists have argued that the method is flawed for several reasons. In particular, they assert that the method may produce unreliable confessions. Len Hartnett, an Australian lawyer for a Lorenzo Fatava, who was convicted in part using a confession obtained from this type of operation, argued that the police officers encourage confessions, "telegraph what they want to hear," and act as an authority figure to the suspect who is in a relatively powerless position. In short, the main concern of defence lawyers is that this procedure may cause innocent people to confess wrongly, and that the "Mr. Big procedure is a fundamentally deceitful exercise.” 
Prosecutors have countered that a confession alone would never be considered sufficient evidence to prosecute a criminal in these cases, and that additional evidence would be necessary.
Mr. Big Documentary
In 2007, Tiffany Burns directed a documentary entitled Mr. Big that examined this method. The movie includes interviews with targets of the operation, their families (Burns herself is the sister of Sebastian Burns, who was convicted of murder in part due to being caught by a Mr. Big operation), and RCMP videos of various aspects of Mr. Big operations.
