It happens all the time, saying something to the wrong person can easily get you killed and if the street is your life then the odds increase exponentially. It's a given once you've accepted a life a crime as your profession, trust no one and no one is your friend. I've ridden with homies in my truck that were packing claw hammers under their Northface bubble jackets and if you said the wrong thing to them, you were gonna eat a Black and Decker, straight up. One of those things punches a hole in your skull and pushes the bone into the brain which swells up like a balloon in your skull. If they can't keep it from swelling, they have to drill holes to relieve the swelling.
