(CBC News) – Some Tasers deliver a higher level of electricity than the manufacturer promises, reveals a series of tests on 41 stun guns that was commissioned by CBC News and Radio-Canada.
The abnormal X26 model Tasers were manufactured before 2005, prompting some scientists to suggest police should stop using any older versions of the stun guns until they can be tested.
Of the 41 Tasers tested, four delivered significantly more current than Taser International says is possible. In some cases, the current was up to 50 per cent stronger than specified on the devices.
The tests, conducted by the U.S.-based lab National Technical Systems, used X26 Tasers from seven police departments in that country. Each weapon was fired at least six times.
Arizona-based Taser International makes virtually all the stun guns being used by police forces. The technical term for a stun gun is conductive energy weapon, or CEW. They are intended to incapacitate people with an electric shock.
The RCMP says it has pulled a random sample of some of the forces’ Tasers for testing based on the results of the CBC News/Radio-Canada investigation.
“Given that you have raised this issue with us, we are taking steps to take CEWs out of our inventory devices that have deployed across the country, we are gathering up samples from each of our divisions, every province and every territory and we will have them independently tested,” RCMP Commissioner William Elliott told CBC News at a recent policing event.
A force communications official, Supt. Tim Cogan, informed CBC News late Thursday that preliminary test results showed the sample of Tasers operated within the manufacturer’s specifications.
Cogan said the tests were conducted at an accredited, independent laboratory in Ottawa, but didn’t provide details on how many Tasers were tested or which lab conducted the analysis. The RCMP is still awaiting final test results.
“The RCMP recognizes that any use of force, including the CEW, carries risks, both to the public and to the police,” Cogan said in a letter to CBC News.
“We do not take the use of force lightly. Ongoing assessment of the tools provided to our members and of the policies that guide their use is essential to mitigate these risks.”
Pierre Savard, a biomedical engineer at the University of Montreal, designed the technical procedure for the CBC’s testing based on Taser International’s specifications.
Savard told CBC News it is scientifically significant that about nine per cent of the Tasers fired in the tests delivered more current than they are supposed to do, especially since he believes no one is verifying the company’s claims.
“I think it’s important because Taser is not subjected to international standards,” Savard said.
“When you use a cellphone, well, cellphones have to respect a set of standards … for the electric magnetic field that it emits. The Taser, well, nobody knows except Taser International.”
Savard said the cause of the increased current could be either due to faulty quality control during the stun guns’ manufacturing or electrical components that deteriorate with age.
The findings are troubling, since police officers are trained to aim a Taser at the chest, said Savard, who studies heart rhythms and how they are affected by electrical stimulation.
“When you combine an increased current intensity with a dart that falls right over the heart for somebody who has cardiovascular disease or other conditions such as using drugs, for example, it can all add up to a fatal issue,” Savard said.
Police forces across North America assure people that Tasers are safe. The manufacturer, Taser International, has said its product has a higher safety margin than Tylenol.
Taser International said they couldn’t provide someone for an interview before the CBC published results from the tests.
However, Magne Nerheim, Taser’s vice-president of research and development, sent a written response to the results, in which he called the four malfunctioning Tasers an anomaly — one that could be explained if the weapons are not spark tested on a regular basis.
Nerheim also suggested the testing be repeated to verify the results. He made no comment about the age of the Tasers and whether there could be an issue of reliability.
During the tests commissioned by CBC News and Radio-Canada, three of the weapons didn’t fire, even with charged battery packs. Those were set aside and not counted in the final results.
But a Taser that doesn’t deploy can potentially create a safety issue for a police officer, Savard said.
“When we are talking about Tasers that don’t function, I think it is dangerous for the policeman who would try to use the Taser and the individual response can be aggressive,” he said.
The CBC showed the results to several electrical engineers as a peer review of the analysis. They agreed that at the very least, the Tasers made before 2005 should not be used again until they are tested and proved reliable.
Is anyone surprised. A year before, CTV reported the same thing and (in my view) Taser International lied it’s way out of that too.

It sounds strange to me that with all the tecknology we have today and all the over sights in place that no one actually did an independent test to see if this weapon was safe to use.
I’m embarassement, shocked and appauled as I think of the many who have died while we have all been assured world wide by our very own justice system that this stun gun was safe and look at the results now and at the waist of life.
Have we slipped that far back in the dark ages that we have turned into self serving apparent killers who turn a blind eye to what is right.
Have we now crossed the like and joined the ranks and files of those who take life instead of serving and protecting and when it goes wrng use any means to justify the end results?
It seems strange that now that this is out we step up to the plate and check the findings… what an embarassement and what a dangerous game we are playing as we the self proclaimed sane join the ranks of the insane.
Insanity: is to do the same thing over and over again and expect different results.
It’s even worst than that.

TASER INTERNATIONAL OFFICIAL STATEMENT (Source CBC):
“TASER International has reviewed the testing results from the National Technology Systems study various TASER X26 electronic control devices as provided by the Canadian Broadcasting Corporation. The results from the testing are generally consistent with the specifications provided by TASER International and which would be expected from such tests.
TASER acknowledges that there are four data that appear to be outliers — instances where current increased as resistance increased, which would not be expected based on the laws of physics. TASER International intends to contact NTS to suggest that the tests be repeated to verify the results.
TASER International appreciates the continued interest in TASER technology, and sincerely hope that the CBC report will focus on the proven injury reductions law enforcement experience with this technology, rather than using engineering minutiae to confuse the viewer and create a false sense of controversy over a test that confirms the output of TASER X26’s are consistent, and well below acceptable safety thresholds.”
Amnesty urges moratorium on Taser use after CBC/Radio-Canada prob
December 5, 2008
CBC News
Human rights group Amnesty International is renewing its call for a moratorium on Taser use after recent tests commissioned by CBC News and Radio-Canada found some of the stun guns deliver a higher level of electricity than the manufacturer promises.
The tests, conducted by the U.S.-based lab National Technical Systems, used 41 X26 model Tasers from seven police departments in that country. Each weapon was fired six times.
Of the 41 Tasers tested, four delivered significantly more current than Taser International says is possible. In those cases, the current was up to 50 per cent stronger than specified on the devices.
The abnormal X26 model Tasers were made before 2005, prompting some scientists to suggest police should stop using any older versions of the stun guns until they can be tested.
The human rights group has said it believes police forces around the world have relied too heavily on the manufacturer’s safety claims. It wants to see more independent tests.
“The fact that Tasers were firing above their specified limits then raises questions as to what of the thousands of Tasers that are out there across Canada and across the United States, how often are they misfiring,” said Alex Neve, secretary general of Amnesty International Canada.
Arizona-based Taser International makes virtually all the stun guns in use today. They are intended to incapacitate people with an electric shock.
The RCMP says it pulled a random sample of some of the force’s Tasers for testing, based on the results of the CBC News/Radio-Canada investigation.
A force communications official, Supt. Tim Cogan, informed CBC News late Thursday that preliminary test results showed the sample of Tasers operated within the manufacturer’s specifications.
Pierre Savard, a biomedical engineer at the University of Montreal, designed the technical procedure for the CBC’s testing, based on Taser International’s specifications.
Savard told CBC News it is scientifically significant that 10 per cent of the Tasers fired in the tests delivered more current than they are supposed to do, especially since he believes no one is verifying the company’s claims.
“I think it’s important because Taser is not subjected to international standards,” Savard said.
“When you use a cellphone, well, cellphones have to respect a set of standards … for the electric magnetic field that it emits. The Taser, well, nobody knows except Taser International.”
Savard said the cause of the increased current could be either due to faulty quality control during the stun guns’ manufacturing or electrical components that deteriorate with age.
The findings are troubling, since police officers are trained to aim a Taser at the chest, said Savard, who studies heart rhythms and how they are affected by electrical stimulation.
“When you combine an increased current intensity with a dart that falls right over the heart for somebody who has cardiovascular disease or other conditions such as using drugs, for example, it can all add up to a fatal issue,” Savard said.
Need time to examine results, Taser says
For years, police forces across North America assured people that Tasers were safe.
Taser International has said its product is “safer than Tylenol.”
Taser said that because of the time needed to analyze the test results and the U.S. Thanksgiving holiday Nov. 27, the company couldn’t provide someone for an interview before CBC News made its results public.
However, Magne Nerheim, Taser’s vice-president of research and development, sent a written response, acknowledging the CBC tests show four of the Tasers malfunctioned.
Nerheim called the malfunctioning an anomaly — one that could be explained if the weapons are not spark-tested on a regular basis.
Nerheim also suggested the testing be repeated to verify the results. He made no comment about the age of the Tasers and whether there could be an issue of reliability.
During the tests commissioned by CBC News and Radio-Canada, three Tasers didn’t fire, even with charged battery packs. Those were set aside and not counted in the final results.
But a Taser that doesn’t deploy could create a safety issue for a police officer, Savard said.
“When we are talking about Tasers that don’t function, I think it is dangerous for the policeman who would try to use the Taser and the individual response can be aggressive,” he said.
The CBC showed the results to several electrical engineers as a peer review of the analysis. They agreed that, at the very least, the Tasers made before 2005 should be withdrawn and not used again until they are tested and proved reliable.
