I've got family in Springfield, Ohio.
Springfield is a nice town. Central Ohio, far enough from Columbus to filter out most of the riff-raff. They called me about a week ago to let me know there had been a home invasion/attempted robbery ON THEIR STREET.
The wife/girlfriend (my uncle's not sure of their marital status, as if that matters to the story) had just gone to bed when a knock came on the door. Hubby/BF answers it, gets bowled over as two armed men rush in. He fights them in the entryway, trying to stay between them and his significant other. She hears the fighting and yelling, comes out of the bedroom with a handgun. One BG makes it onto the front porch where he bleeds out, the other BG is wounded and apprehended. A third, the getaway driver, is seen only as a shape in the car as it leaves. Hubby/BF sustains a razor burn where his lady's bullet passed very, very close on it's way to BG #1.
So tell me again how paranoid it is to go armed in your own house.
Crap like this always happens to the other guy. To the schmuck on the other side of town, you ARE the other guy.
