Our President has admonished us that "Communities of color aren’t just making these problems up." I never thought they were. On the other hand, police officers working in neighborhoods where apparently it's OK to rough up store clerks and get in cops' faces (not to mention loot and burn stores) aren't making up their problems, either. I don't think a police officer is ever obligated to let a furious 300-lb. guy--armed or unarmed--close on him without shooting to protect himself.
