Was going too fast to stop for traffic lights. Amber means STOP if its safe to do so. Not ignore and go thorough when its red. If there was a traffic light camera you'd have been caught. But then I guess you'd have approached a bit slower. Bet you didn't do that on your HGV test!
The only thing cops do these days. Park on sidewalks and cycle lanes, blocking passages, harassing innocent people, and not to forget: running people over (see SC57JUN). How hypocrit. We're better off without them.
I hate your trousers.
