But if you believe (or know) that the cop stopping you is violating your rights or is acting like a bully, I guarantee that the situation will not become easier if you show your anger and resentment. Worse, initiating a physical confrontation is a sure recipe for getting hurt. Police are legally permitted to use deadly force when they assess a serious threat to their or someone else’s life. Save your anger for later, and channel it appropriately. Do what the officer tells you to and it will end safely for both of you. We have a justice system in which you are presumed innocent; if a cop can do his or her job unmolested, that system can run its course. Later, you can ask for a supervisor, lodge a complaint or contact civil rights organizations if you believe your rights were violated. Feel free to sue the police! Just don’t challenge a cop during a stop.Of course, the system is highly effective at identifying examples of police officers abusing their power.
