I'm really sorry, kimba.
I hope you don't get a gun, because IMHO, they cause more violence than they prevent. I can visualize quite a few scenarios where you get hurt because you had a gun and only one where you get saved by a gun. It's only in the movies that the good guys with the guns beat the bad guys with the guns. In real life the good guys are too good and the bad guys are too bad. They're faster than you, meaner than you, more experienced than you and most importantly they have nothing to lose. That's because they're punks. They're not afraid of hurting you and going to jail and you just don't have it in you to be that ruthless and that savage.
So I'd ignore whatever right-wing fantasies you hear about gun ownership. I'd say there's a 5% chance it could save your ass in a tight corner and a 95% chance it could really fuck you up.
If you feel there's a chance they might break into where you live, that's a whole nuther story, of course. Then I'd want to check with a lawyer, a gun shop and a gun club, explore the options, maybe speak to a couple of cops if you know any well enough to get their honest opinion, and make an informed decision. I sure as hell hope you won't need one.
