New research adds evidence to the theory that stun guns, or tasers, appear to be safe for most people.
Researchers at Wake Forest University reviewed almost 1,000 cases involving the use of stun guns by police in apprehending a difficult suspect. And they found that 99.5 percent of people tasered suffered either a mild injury, like a bruise or scrape, or nothing at all.
Only 3 out of the thousand needed to be hospitalized, and two of those were injured when they fell after being tased. The third person went to the hospital days later and it's questionable whether that injury came from the stun gun.
The study was funded by the National Institute of Justice.
