In a nice neighborhood where my family lived while I was in my teens, there was (1) a murder by a mugger, over $1 (that is all the victim had on him), which happened in the afternoon, on the street just a few houses from ours; (2) two separate fatal hit-and-runs, the pedestrians were in the cross-walk, also happened in afternoon and on same street and in front few houses down from ours; a rape of a sandwhich shop teen girl, around 5 pm, still daylight, a few blocks down. The poor girl had her clothes stolen and she ran home. These all happened with two years.
I move to my own place in my 20's, in the same nice town. One of the neighbors were hippy-types, and when I had to park on the street coming home from work, they were paranoid and would shout at me, asking who I was and why I was parking there. I walked every morning and some evenings so I was no stranger, and lots of people parked on the street. I tried to avoid them, thinking they could be on drugs. A time later, the neighbors on my other side had several police cars, sheriff department cars all outside surrounding that house: a big drug bust! Somebody told me the parents had moved out because their children were involved in the drug traffic.
Scary also, as I did a lot of walking of that neighborhood, when I came back home to watch tv, on the news it was reported a nearby drug (legit) manufacturer had leaked harmful chemicals from a truck, in the street gutters -- right there where I did walking. We were advised not to walk there, let children play or pets there. Okay, but why wasn't there any warning signs or anything at the location? Why did I have to hear it from a tv news broadcast? That was scary.
