From what I gather, he was stopped, but before it was sorted out he drove off, hitting a copper, then he drove for 17 minutes being followed by police with lights and sirens going. Now if he truly believed he was having a police escort then I would say hes not right in the head and not safe to be on the road (after driving of before being dealt with). For all the police knew he was doing a runner. Dont really see why a copper needed to jump on the bonnet and smash the windscreen mind.
Would I like it to happen to a relative? Of course not, but if it did Id be asking should he be driving?
As for police being Jealous, come on police earn a good wage any copper ive known of drives a nice car and has a nice enough home.
