Yeah, bad guys don't like guns... especially when they're aimed at them.
Buddy got robbed, called the police then me. I showed up before the police (surprise,) and cleared the house. Police filed a report then left, and I hung out just for the heck of it... of course I had my .45 on me.
Sure enough, about an hour later I hear some jimmying at the back door, so I walk real slow with my pistol drawn, wait at the door. Kid jimmies the door, and opens it to the barrel of a .45. He was gone before you could say "GET OUT!" Hahahaha.
And the house has never been messed with since. Imagine that. I also encouraged my friend to get a gun first instead of a new Xbox360. He thinks that's a good idea.
