Why are people so RUDE to Law Enforcement

This is a duet video i made, to make a point about being polite and Courteous while dealing with any Law Enforcement. Listen not all are bad. these guys were just doing their jobs. they saw someone with an assault rifle and god only knows what else and they acted on that info. this guy did not have to be a prick about it. the guys is within his right to do what he was. but just be nicer when explaining when confronted. you dont want to be a statistic.
