Eddie,
Depending upon where you reside, stun guns and Tasers, which can be quite effective, may not be legal. Some cities in the U.S. have taken steps to outlaw them because the thugs use them as well. When such ineffective laws such as those that outlaw guns go into effect the only people effected are honest, law-abiding citizens. The criminal element could care less--that's why they are criminals. There's an old saying in this part of the world "Never bring a knife to a gun fight1" Makes perfectly good sense to me.
