Yes, I'm a boomer, so I've lived long enough to see it too. It's actually mixed. Some forms of violence are more common now, but over all, violence has gone down. According to FBI statistics, murders, rapes, and assaults are ALL down, even in urban areas, from what they once were. I discussed this with an old professor of mine, and he thought that perhaps this was simply because of demographics, that most violent crime was committed by young men, and quite frankly, there are just fewer young men these day than there used to be (boomers are aging, Xers are getting there, younger generations are simply smaller). I dunno. Maybe.
