Police departments across Canada, including the Royal Canadian Mounted Police, are pulling older Taser stun guns off the streets after a study that found the weapons can deliver more power than the manufacturer says is possible, reports the Arizona Republic. Police departments in the U.S. appear to have taken no similar action. Taser International responded to the study, commissioned by the Canadian Broadcasting Corp., contending that the research is flawed.
“It is unfortunate that false allegations based on scientifically flawed data can create such uncertainty,” said Steve Tuttle, a Taser vice president. Taser’s assertions about specific data flaws contradict company documents and a letter from one of its top scientists. The study found that four of 44 stun guns of the X26 model used most by police departments fired jolts that were 47 percent to 58 percent higher than the manufacturer’s specifications. An accompanying medical analysis concluded that the higher jolts pose as much as a 50 percent risk of inducing cardiac arrest in some people and that stun guns firing at expected electrical levels pose some risk. Taser maintains that shocks from its stun guns can’t kill.
