The facts are out there: some LEOs use TASERs in an inappropriate fashion; little old ladies, handicapped people, etc. And it is also a fact that a shot from a TASER can cause long-term problems (even death, the longest-term problem). HOWEVER, I would rather get a TASER blast than a 9mm blast. And, I would (I think) rather be TASERed than take a night-stick to the side of a knee (though I will admit I haven't done any research to verify this position). What I am trying to say here is that the valid uses of non-lethal electronic control mechanisms have saved many more lives than they have taken. It gives LEO an option. And, while it may not be appropriate when writing a jay-walker with a large mouth, the LEO on the scene should be the one to make that call. And I am in the camp of those who feel that BGs pretty much surrender their rights to polite behavior from others when they do whatever it was that made them a BG. (For example: I was disappointed that the molesting cretin in Phoenix last week didn't resist enough to warrant two to the chest and one to the head.)
The other commonly used option is swarming an offender and I have witnessed that go rapidly nuclear. LEOs in numbers taking down one BG have frequently escalated the action well beyond the force necessary to subdue and it becomes a "punish the perp" exercise. Bruises to kidneys and livers, broken collar bones, broken jaws, brain damage are all possible if not likely outcomes.
So, my vote is let the LEO make the call. If he/she makes the wrong call, give a little one-on-one Come to Jesus meeting. If the wrong call becomes a habit, that LEO needs to find another line of work. But keep the 9th Circus Jerks of Schlemiels out of it.
