Tazer.
Unfortunately, in some jurisdictions, tazers are being slammed as dangerous or lethal, so law enforcement is limited to clubs or firearms. IMHO, this is stupid considering that firearms are mostly lethal.
Just had the local chief of police come in to talk about safety. Although he recommened mace (as an alternative for those scared of guns) he made the point that mace doesn't work on everyone, himself an example. He also made a similar point about tasers.
If your life is in danger, political solutions are not the best solution if you want to live.
Prolly not. If this guy was hopped up enough to ignore the face full of pepper spray they gave him first, the tazer would probably have had no effect on him.
