How to interact with a police officer(s)

To rephrase.
Cops have to deal with liars, thieves, murderers, thugs, robbers, woman abusers, rapist, child abusers, child rapist, speeders, drunks, drug addicts, dealers, possible terrorist and dumb asses on any given day.
In general, *** holes.
Shut up and comply when interacting with them and prove you are not one.
99.9 percent of the time that is all it takes.
The cop is just doing his job.
