My observations
Coming from no particularly involved point of view, here's my take.
A) more cars. Period. I don't know but I'd bet that vehicle accidents and deaths are up across the board regardless of occupation. Of course those that drive for their job (cops, taxi's, truckers, etc.) play those odds more than someone who drives three miles to work and two to church on Sunday.
B) High speed chases are morally criminal. Use a radio and cooperate with surrounding departments. We can all agree that fast response time is good response time, but too often we read an obituary in the paper for an uninvolved person, a police officer or the suspect. Before you say it, I know, don't run. I agree, but don't endanger yourself or others because you're too @#$% macho or bucking for brownie points to call for B/U and assistance. If the S.O.B. runs, you can tail him at a safe distance and observe without running me or my family over to catch him.
C) As for the seeing police cruisers run red lights, I stopped counting the times a Cleveland cop would sit at a light for a few minutes, get frustrated, pop on his lights and blow through the light. Then promptly turn off the lights.
