He hasn't shot any cops because he knows they are armed and one might get a shot at him. Most citizens don't walk around with a gun on their hip. If they do carry they conceal it. He knows that he can get them before they can even think about it. It is alot easier to kill a citizen than it is to kill a cop.

Not if he nails the intended victim from behind. (Do they have bulletproof hats?)
