<P> In October 2007, there was an incident at Vancouver International Airport involving new Polish immigrant Robert Dziekański . Dziekański was tasered five times during the arrest, became unresponsive and died . The incident was video recorded by a civilian who turned it over to police, then sued to get it back for release to news outlets . The official inquiry found the RCMP were not justified deploying the taser and that the officers deliberately misrepresented their actions to investigators . The incident affected taser use in Canada and relations with Poland . </P> <P> During the 2010 G - 20 Toronto summit protests, police enacted regulations the Ombudsman found contributed to "massive violations of civil rights ." One regulation made the security zone public works and police interpreted this to permit them to arrest anyone not providing identification within five - metres of the temporary fence . There were 1,118 arrests with 800 released without charge, Police Chief Blair conceded later no five - metre rule existed in law and Ontario Premier Dalton McGuinty was criticized for allowing this misinterpretion . In September 2011, officers who removed their name tags during the G - 20 protests were refused promotion . </P> <P> Security officers in Metrotown, Burnaby mall demanded pictures taken of an arrest be deleted from a teen's camera . This led to a verbal confrontation and the RCMP handcuffing the teen and cutting off his backpack to search it . While the mall supports its officers actions according to the teen's lawyer: "private mall security guards and police have no right to try to seize someone's camera or demand that photos be deleted--even on private property ." </P> <P> The collusion between local gangs and police officers is a serious problem in many Chinese cities . Local gang bosses make use of personal networks to bribe police officers, and police officers seek corrupt benefits by safegurading their illegal businesses . The most widely publicized case is the Wen Qiang Case . Wen Qiang a deputy police chief, along with family members, was arrested as part of a massive crackdown on corruption of the People's Armed Police and organized crime in Chongqing in late 2009 . His crimes included bribes, rape and failing to account for assets; Wen was executed in July 2010 . The trials highlighted the continued use of torture by police to obtain confessions, despite laws implemented in June 2010 excluding tortured confessions being used in trials . </P>
