A criminal that would attack a police officer is a rare individual...not your run of the mill criminial. Your idea of a common street punk is accurate. Common street punks are not the type that would attack a police officer.
In my opinion.
gotta say that a lot of dead police would contradict you on that.
I think most here know that if SHTF in Any time-line, you stop the threat as fast as you can.

Mine also. Not since the Black Panther days decades ago did that occur regularly. One would have to be suicidal to even thing about doing something like that.
