All police departments allegedly try to maintain professional standards during traffic stops, although they are not required.
This also goes for the driver, small things like not rolling down the window fully, recording the incident, not giving consent, are all critical rights.
An activist in the video above states:
“THE COP WANTS TO STICK HIS HEAD IN YOUR WINDOW AND SMELL IF YOU’VE HAD ALCOHOL OR DRUGS. THAT’S AN UNREASONABLE SEARCH“
The video goes on to explain how to minimize your interaction with police, and to the average person I would suggest most of these things, with the exception of ‘not recording‘ due to fear of ‘heightened officer awareness‘.
