Wondering what the cops did to piss him off ..." So you're not a cop hater yet you jump to that conclusion.

If the car was full of nuns I would have said "Wondering what the nuns did to piss him off".

Clear enough yet?

Yes, my point exactly.

In your formulation someone must have “pissed him off”, therefore justified; in this case cops.
