I think you guys are having the wrong argument.
Violent crime is down, but the new dangers we face make us less safe than we've ever been in our lifetimes, IMO.
I don't think you can take the cautions you did 15 years ago and still feel reasonably safe. What I mean by that is, if you don't want to be mugged or killed, you pretty much know what parts of your community to stay away from.
Now on the other hand, we have people among us who are willing to go to great lengths to take out mass numbers of people in ambush attacks. To me, this is quite different than violent crime that you would normally read about in the paper and say "yeah, bad neighborhood, or wrong place at wrong time."
You have to keep this threat in perspective. I don't know if I'm a pussy, but I think twice now about where I take my family on vacation, or where and when we do things where I know they'll be large numbers of people. I've never worried about going to concerts or shopping malls at Xmas time. Now I do.
