....with open carry, how are the cops supposed to know who the bad/good guys are?

Hostile aggression toward police, guns pointed toward police = bad guys.

No hostile aggression toward police, weapons slung, not pointing at police, = neutral or good guys.

Not hard, been there, done that.

I wonder how calling "I've got your back, officer" would work.
