For homicide this is very correct. You could live dead center in the statistically most violent block of Chicago and still cut your personal risk of being a homicide victim by 1) not being a criminal, and 2) not posting diss raps to your 11 followers on Soundcloud. There are not really dangerous neighborhoods but there are dangerous social networks.

I'm also a big believer that "head up, voice down" will reduce your likelihood of becoming a target.

People don't usually bring trouble to themselves for no reason. Don't give them a reason.

And not having any vehicle problems, because you usually only are rolling through bad areas to get to better areas. Most people in violent cities have no occasion to stop in violent areas. On one occasion I was forced to work overnight for critical hospital operations in a bad part of town, on my way back my tire went flat and when I was distracted fixing it the locals noticed I was weak and they put a gun to my head.
