Vancouver, Canada (AHN) - A tearful Zofia Cisowski, mother of the Taser gun victim at Vancouver Airport, called Thursday for a moratorium on the use of the stun gun.

What added to her grief because her reunion with her son would no longer be possible was discovering she was told a different version by authorities how her son, Robert Dziekanski, died at the hands of the Royal Canadian Mounted Police. Cisowski found out the real version only after she viewed the videotape of her son's death.

"The story was very different than I was told by the authorities," Cisowski said, quoted by the Canadian Press.

The Polish migrant blamed the death of her son to the two hits he sustained from the Taser. Dziekanski just arrived at the Vancouver Airport and was disoriented and confused from the long trip and inability to speak English, causing him to become unruly. "He did not deserve the treatment he encountered at the airport," the Canadian Press quoted Cisowski.

Because of the tragady, Cisowski said she had lost confidence and faith in the RCMP and Canadian authorities.

At the same hearing, Tom Smith, chair of Taser International, the manufacturer of the stun gun, admitted the weapon is not risk-free. Smith emphasized the word non-lethal should not be understood to mean safe.

Smith's statement contradicted that of MP Ujjal Dosanjh, attorney general at British Columbia in 2000 when the Tasers were introduce to the RCMP. Dosanjh said he was assured of the stun gun's safety.

The Taser is being used by 350,000 police officers in 40 nations.
