Sigh..
did you not read what was written?
the person using the taser would likely use it with confidence knowing it might only maim the target, but as it is now being shown, THAT is not the consistent result.
the taser operator can now regard themselves as cold-blooded killers, because that has been the actual result.
apart from my obvious dislike of the weapon, I'm also pointing out the lifelong impact (unintended) on its user - which is, at least, unsatisfactory.
