I see what you are saying but the two incidents are separate. The copper could just say that he intended to pull you over at the next safest place. That is his discretion not yours, don't forget while he was following you, he would have been radioing in to find out if your car was insured etc. It could have been that he just got all the information in just before the second set of lights and that was when he decided to pull you. The fact he ran a red light doesn't matter because he was technically in pursuit. He doesn't have to have blues and two's on to do that, (at the moment, although there is call for this to be mandatory).
Even if you went to court, that part of the film is not relevant to the incident and would be dismissed.
Sorry but I think you have been a victim of target based policing.
