couple years ago I was bombing down a hill on a longboard, and an unmarked police vehicle blew through a stop sign (no lights) and decided stop halfway into the intersection... My only choice was try to jump.... needless to say it didn't work. I slammed into the front quarter panel and flipped over the hood of the car.... The police officer inside said "my bad" and then drove off.... I couldn't get a good look at the plate, I laid there with 3 broken ribs, a dislocated shoulder, and a broken phone with screen glass stuck in my leg until someone actually got out of there car to help me to the sidewalk...
Later that day I went to the police department to file a report, they said that "dashboard cameras are not evidence enough to incriminate a L.E.O..... in the event that a "crime" is committed by a police officer they are officially required to report it, and since there was no report made by the U/C officer in question, I was basically told that I was lying....
The desk jockey said if it did happen, it was probably my fault anyway, and flat out refused to write a report for me....
