i didnt feel like doing all the of reading but i had a friend who was a passanger in a car when a cop did that....
They were going about 70 - 80, cop puts on his lights, the guy starts slowing down to pull over, the cop rams into the back of the guy which spins both my friend and the driver around in the car and then they flip over the median... oncoming cars instantly kill the guy driving and my friend is severley injured. In the end the cop said he dropped his CB radio and accidently hit them frmo behind, nothing happens to the cop but the burden of having killed someone... In that case the cop injured my friend, killed the guy, and probably injured some people in the oncoming traffic...
