So after watching all the crap Zimmerman had to go through and the way the media jumps on anyone who uses a gun for self-defense these days, I got to thinking about using "less lethal" ammunition for home or self defense. A quick search found 12 GA shotgun ammunition for about $5-6 per shot and pistol ammunition for about $3 per shot (although they say the pistol ammunition will not cycle the action on semi-automatics). At that cost, I can't see doing much practice with the ammunition and I prefer the idea of practicing as you're going to fight but ... the prospect of avoiding the kind of crap Zimmerman went through might be worth 5 or 6 rounds a quarter or even month ...
Not putting the assailant down permanently is possibly an obvious disadvantage -- but legally might be an advantage. I think most of us agree the very act of self-defense is often enough to dissuade many attacks, especially the kind of mall or school assaults we've seen recently.
Any other advantages or disadvantages beyond cost, legal repercussions, or possible follow-up attacks? Is there a potential burgeoning market here for home- and self-defense?
