The news recently had a black guy being arrested for jaywalking of all things getting into a fight with the two white police officers, then being shot over it. Only one of lots of examples of black people being detained for a minor infraction and then escalating the situation into something life threatening. There is a third option to fight or flight and it would be, "Yes sir, where would you like me to stand and receive my citation?" I have little doubt that there is racial profiling, but what is it that makes people, particularly minority people, be combative over near nothing?
Possibility that he had a half dozen felony warrants out.
