When I was living in New Hampshire there was a big case in Cambridge, MA where 2 white kids playing the knockout game (that's even what they called it in the paper) ended up killing an MIT student. The one kid who did the punching showed up for his hearing with a broken hand. That was in the early 1990's.
When I was in high school (now we're talking 1970's)one of our teachers talked about how when he was growing up in Jersey City he and his friends used to pile into a car, draw cards and in order pick a street, let one person out and he would have to fight the first man who walked by. That would have been in the 1950's.
When it hits close to home, you start to think. I don't go anywhere without my 1911 or the 460 when in the woods, but in Alaska everybody does that. My nephew came up hunting last fall and was telling me that where he lives (outside D.C.), it's illegal to carry, unreal. He tells me that very few people have pistols on their belts due to the laws. I told him that I just couldn't call a place like that home.
