As has been pointed out (and explicitly noted by the Braidwood Inquiry), virtually all taser demonstrations and training sessions involve the taser darts being fired into the idiot volunteers' backs, and rarely their chests.
As an indicator of taser safety, they're FAKE. It's plainly obvious that the purpose of this backs-only policy is to boost up the number of non-lethal deployments. Keep the taser current well away from any cardiac paths.
A related detail that I recently noticed is that the eye protection worn by the idiot volunteers is obviously designed to provide better protection from the front, than from the rear.
The convex shape of the lenses on the safety goggles would effectively deflect incoming taser darts arriving from the front.
But that same shape provides less protection if the taser dart is fired from the back, just happens to whistle past the idiot volunteer's ear, then is captured by inside concave surface of the goggles, and thus deflected straight into the idiot volunteer's eyeball.
Obviously the idiot volunteers should turn around and face the taser darts head-on.
It's all fun and games until someone looses an eye.
