I live right off campus in a pretty rowdy neighborhood. Some jackass broke into my apartment last fall. I knocked him to the ground, pulled my knife, and he ran away. It worked out good for the both of us. Most people usually bring a weapon with them when they break into someone's house, so I was ready to battle to the death if need be. Good thing that didn't happen. I'm pretty sure he was at least buzzed though. Lots of drunken parties in my neighborhood. Probably trying to show off. I've thought about getting a gun since then. I did buy an airsoft and painted it to look like a real gun though. I also bought a solid black curtain in case people could see my HDTV and xBox 360 in my living room through the vertical blinds, which was pretty apparent from the outside and probably made for a good target. My roommate and I also keep "weapons" in the living room now, like his lacrosse sticks, my tennis rackets and heavy tripod, and scissors / utility knife in the pen cup on the coffee table.
