Driving To Fast ?

Have you ever been driving along minding your own business and heard sirens ? The law states you must pull over and stop so the ” Emergency ” vehicles can safely go by. I can see fire trucks and ambulances going way to fast to get to the accident scene. It appears that the police drive at excessive speeds most of the time. Is there a statistic for accidents caused by excessive speed of law enforcement on the way to a ” Police Call ” ?
