USA: Safety of Tasers questioned as death toll hits 334-mark

Industry claims that Taser stun guns are safe and non-lethal do not stand up to scrutiny, said Amnesty International today as it called on governments to limit their deployment to life-threatening situations or to suspend their use.

The call came as the organization released one of the most detailed reports to date on the safety of the stun gun. The report “USA: Less than lethal?” is being published as the number of people who died after being struck by Tasers in the USA reached 334 between 2001 and August 2008.

“Tasers are not the ‘non-lethal’ weapons they are portrayed to be,” said Angela Wright, US researcher at Amnesty International and author of the report. “They can kill and should only be used as a last resort.”

Amnesty International’s study -- which includes information from 98 autopsies -- found that 90 per cent of those who died after being struck with a Taser were unarmed and many did not appear to present a serious threat.

It is unwise and illegal to threaten another person with a weapon unless you have good reason to do so. In many states the person you threatened might well be able to use a 'stand your ground' defense. Much would depend on the events that led up to the confrontation.
