The police initially took possession of the memory card containing the video as evidence, stating it would compromise the investigation if it were released to the public at that time.

The final inquiry report, released on June 18, 2010, concluded that the RCMP were not justified in using a taser against Dziekański, and that the officers later deliberately misrepresented their actions to investigators.

[11] He used chairs to prop open the one-way doors between a customs clearing area and a public lounge and at one point threw a computer and a small table to the floor before the police arrived.

[13] Four RCMP officers, constables Gerry Rundel, Bill Bentley, Kwesi Millington, and a supervisor, Corporal Benjamin Robinson, arrived and entered the customs room where Dziekański was pacing about.

[18] Constable Millington testified that he deployed the Taser four times, but he believed that in some of those instances the probes may not have contacted Dziekański's body.

[13] In 2013, the BC Coroners Service ruled the death to be a homicide, citing a heart attack caused by the repeated jolts.

[26] The RCMP officers involved in the Dziekański death, constables Gerry Rundel, Bill Bentley, Kwesi Millington, and supervisor Corporal Benjamin Robinson, have been widely criticized for their handling of the incident.

The BC Civil Liberties Association filed a complaint in 2007 arguing that the evidence shows that the Taser was not used as a last resort and condemning the RCMP for its attempt to suppress the video and for casting aspersions on the character of Dziekański.

[29][30] An RCMP spokesman, Sergeant Pierre Lemaitre, was heavily criticized for providing a false version of events prior to the public release of the video.

He stated that Dziekański "continued to throw things around and yell and scream", after the arrival of the police officers, which was later revealed by the video to be false.

[31] Sergeant Lemaitre committed suicide in 2013 due to his involvement in the case, according to his wife, who alleged he was made a pariah and demoted by the RCMP.

[33] On December 12, 2008, the Criminal Justice Branch of British Columbia issued a statement, finding that although the RCMP officers' efforts to restrain Dziekański were a contributing cause of his death, the force they used to subdue and restrain him was reasonable and necessary in all circumstances; thus there would not be a substantial likelihood of conviction of the officers in connection with the incident and accordingly criminal charges were not approved.

[34] Three of the officers remained on duty elsewhere in Canada, while the supervisor, Corporal Benjamin "Monty" Robinson, resigned from the force on July 20, 2012, prior to a sentencing hearing after being found guilty of obstruction of justice[35] stemming from a vehicle collision that resulted in the death of a 21-year-old Vancouver man.

[46] The human rights group Amnesty International repeated its call for Taser use to be suspended until an independent investigation into the medical and other effects has taken place.

[47] Meanwhile, Canada's seventeenth Taser-related death occurred less than a week later when Quilem Registre died after being tasered by police in Montreal.

Historically, medical science and forensic analysis has shown that these deaths are attributable to other factors and not the low-energy electrical discharge of the Taser.

"[49] Critics, however, point out that "excited delirium" is not recognized in the Diagnostic and Statistical Manual of Mental Disorders and claim that police overuse such so-called conditions as a matter of convenience.

[50][51] While many psychologists argue[weasel words] that excited delirium is indeed a bona fide but rare condition that can cause sudden death,[51] experts say that delirium (without the "excited" modifier) is a well-known condition, but that it is usually triggered by factors such as drugs or a pronounced mental or physical illness and that it is extremely rare for those afflicted to suddenly die.

[52] An autopsy for the British Columbia Coroner's Service did not determine the cause of death, citing no trauma or disease, but noted that Dziekański had signs of chronic alcohol abuse such as atrophy of a portion of the brain, cardiomyopathy and fatty liver.

"[11] On December 12, 2008, the Polish embassy in Ottawa issued a statement stating that the Crown's decision not to charge the RCMP officers was "most disappointing".

[62][63] Canada's then Minister of Public Safety, Stockwell Day, said that he had asked the RCMP for a review on Taser use and that a report was being prepared, and pointed out that several investigations of the incident were already underway.

[66] Both the Toronto Police and the Royal Newfoundland Constabulary, meanwhile, have put large orders of Tasers for their front-line officers on hold.

[67] The Braidwood Inquiry was established by the Government of British Columbia and headed by retired Court of Appeal of British Columbia and Court of Appeal of Yukon Justice Thomas R. Braidwood to "inquire into and report on the use of conducted energy weapons" and to "inquire into and report on the death of Mr.

[75] On June 29, 2010, and prodded by the Braidwood findings, special prosecutor Richard Peck released an opinion there was sufficient new evidence to reopen the investigation into conduct of the four RCMP officers.

In his ruling, Ehrcke said "The Crown has proven beyond a reasonable doubt that Constable Millington gave oral evidence under oath which he knew at the time to be false, and he did so with the intention to mislead the inquiry."

Constable Bill Bentley was cleared of similar charges by Justice Mark McEwan,[79] but as of June 22, 2015 the Crown had appealed the verdict.

[78] More than ten years after the killing on 30 October 2017, the Supreme Court of Canada dismissed the appeals and affirmed the sentences of both Kwesi Millington,[80] and Benjamin Robinson,[81] both of whom were convicted of perjury.

Gary Bass, the RCMP deputy commissioner of the Pacific region formally apologized during a news conference at the Vancouver International Airport on April 1, 2010.
