A lot of people have received shocks from the Taser gun and have survived. This number of people who survived is far more than those that have died.
Amnesty International Canada agrees that most Taser deaths may have happened due to their improper usage. In most cases where the Taser ended up killing the victim was due to the fact that since the officers feel that Tasers are harmless, they may be increasingly tempted to use them frequently but an Officer should know that unless usage discretion is properly determined, Taser guns can lead to deaths.
Stun guns like Tasers are often preferred by officers simply for their easy use, better user control as well as lesser danger to both the officer and the target. If they are used after a proper warning, that if the target does not calm down, a Taser gun is most likely to be used against him, they could stand a better chance of achieving a safe end
