There is a difference in who is getting attacked these days vs past. In the past, the crime was more amongst the people taking part in obviously dangerous things.

Now it feels more like it can happen to anyone. I spent a few years in SF as a child 89-92. Have visited several times a year, every year, since 1992. It's definitely the most run down, dirty, and unpleasant it has ever been IMO. I have luckily never had anything stolen, but I for sure see more broken glass and more broken car windows too.
