"Some shootings, robberies" means that you are at an increased risk of experiencing those things. Life is hard enough, no reason to add the potential for more PITA crap to happen to you if you can avoid it.

Here is an example. My buddy had his stock car radio stolen out of his car during the day in a school parking lot in that neighborhood. A GATED SCHOOL PARKING LOT. Sure no one was hurt, but do you really want to introduce the annoyance of things like that if you can avoid it?

If you don't have to live in a neighborhood where those things occur there is no reason to.
