I am stunned at how ... wrong all of this is. The odds are the same as death by wrist restraints, and most of the time the associated death from tasers is due to complications due to illegal drug use or preexisting heart disease. I've never heard of someone healthy and clean die from being tased. And no, tasers were introduced for the very specific reason to be used in situations where you wouldn't use a gun. Like riots or escaping suspects of violent criminals/suspects. The ... M29 I think the model currently used, has the stopping power of a standard issue M9 beretta, but causes a fraction of a fraction of the permanent damage.
Tasars have ALWAYS been known to be fatal options when used correctly, in one single short burst to drop the suspect. You are, after all, electocuting someone. They just have smaller odds of killing someone than a torso, head, or thigh artery gun shot. This is why tasers were introduced to be used as an alternative to shooting someone with a gun. Not to be used in any situation where you wouldn't use a gun.
Seriously, if the fatality rate was actually that high, would the method of certification the police and military use to allow them to carry and use tasers involve being shot with them first? A lot of the deaths associated with tasers are with people who are drugged out of their minds and violent, or have heart conditions. Sorry, but just the use of one isn't "excessive force" in any way possible.
Again, that's not right at all. Not even close. It isn't "an item used in situations they'd use a gun in," the taser is the option you use in lieu of deadly force. It's what you use when you want to incapacitate someone, not kill them. It's, in fact, one step below deadly force on the Escalation of Force chart.
So a police officer used an item they are supposed to use in situations they would previously use a gun in, to arrest a man with no weapon.
It wasn't excessive force. It was, as far as the case you linked to, a so far unfortunate incident. Calling it excessive force just marginalizes actual cases of real excessive force.
