pacopoolio - Interesting story about your experience with police. What led up to those things though? Did you question or not listen or anything? Did they say get out of the car and you asked why vs just doing it, etc?
Anyway in the area I live in, the past few years almost each year a police officer has been killed on duty. Even on basic traffic stops too. Each time an officer pulls somebody over or approaches for any reason, their is a chance that that person will be armed and will attempt to kill them. Some officers may be power hungry aholes, but sometimes the aggression can be because any resistance increases their chances that this stranger may be dangerous.
The crime statistics are not the stop and search misdemeanors, etc, the FBI posts crime statstics annually and broken down by race, gender, etc, for all crimes from theft, robbing, to drunkedness, etc. Blacks are over 50% for all theft/robbery crimes. They are far below average for drunk crimes, whites are top for that. Asians are the lowest in everything.
