Red traffic lights and police

The following situation: Drive yesterday afternoon on a road where 70 km/h are allowed. Was in a bit of a hurry. When I came near a traffic light, the “preample” flashed (this orange flashing light, which indicates that the traffic light behind it switched to red immediately). I gave full throttle and rushed about 120 km/h (70 were allowed!) over the crossing, but did not make it in time, the traffic light was already almost 1 sec. red when I crossed the crossing. Now my question: If the green boys noticed that I was on the traffic lights in red and that was way too fast (120 and 70 are a difference), could they do something against me? In case of doubt there would be a statement against statement (my girlfriend was still in the car, police officers are usually always in pairs). I mean, they don’t have any proof against me, at the most the license plate they could use. But that’s not enough as proof, is it? In my opinion, they should have turned immediately and persecuted me in order to be able to do something about me. But they obviously didn’t care about me at all. How do you assess the situation?
