It's pretty obvious that the left rear tire blew out and the HPD Crown Vic. Perhaps he was sleeping on the day in class where they went over how to handle your car when it suffers a sidewall separation.He likely over reacted to the vehicle pitching left, and corrected to hard to the right, causing the vehicle to spin right striking the barrier while traveling backwards before bouncing, striking a second time, and spinning partially around to its resting place.No worries, the tax payers will foot the bill! 4951
