My friend got into a multi-car accident involving a cop. Basically, some white van pulled out from a bank without looking, nearly hitting my friend. He swearved out of the way and hit a speeding cop who careened over the median and absolutely destroyed another car (the person inside was OK), but their car was totaled.
Cop knew he fucked up so he didn't give my friend a ticket, but did say that friend's insurance would have to pay for the car he hit (the cop, that is). Long story short, my friend didn't accept it, cop tried to blame everything on friend, everyone lawyered up and both he and the cop have to pay out now. Investigation determined that the cop was indeed speeding. No recording of white van, plus a cop was involved so shit could've been worse.
