Killing someone after you rubbed them is the stupidest thing Americans do, seriously rubbing a person is nothing more than 5 years maybe 10 at max why not quit there ? The cops might even ignore looking for you with priority over a petty $700 but killing a person you now put yourself on a life in prison stand and your case is priority even more important than people who rubbed a bank I mean people are just to dump in this country with committing crimes
