But police? What exactly could police do?
Absolutely. An incident happened to me once in the UK (remember UK law and police procedures may be different). I was walking across a road in tne middle of town carrying a large heavy suitcase, using a crossing where I had right of way over cars. I realized there was a car driving towards me at about twice the speed limit, with no obvious sign of stopping.
I jumped back out of the way of the car, and in the process let go of the case which hit the car. I picked up the car and carried on walking. A few seconds later I was expectedly pushed to the ground from behind by a middle aged man who as "effing and blinding" and accusing me of deliberately attacking his car. I decided the best option was "play dead" rather than get up and provoke any more aggression. Shortly afterwards a woman (a passenger in the car I assume) turned up, called the man off, and they went back the the car and drove off. I got the car number. When I got up I discovered (or assumed) the guy's expensive wrist watch had come off when he pushed me, I had fallen on top of it, and the glass was cracked.
There happened to be a police station only about 200 yards away, so I went there to report the incident, and took the watch rather than leaving it in the street. As with DaveC's questions, the basic response was
Was anybody else involved apart from the two of you? No.
Do you have ID of any witnesses? No.
Have you suffered any personal injury or damage to property? No.
Do you know if you actually damaged the other guy's car or not? No.
Are you sure the watch belonged to the other guy? No.
Conclusion and advice: Throw the watch in the trash can on your way out, and forget about the whole thing. We aren't going to waste our time on paperwork just in case the other guy makes a complaint. If he doesn't know who you are, that's his problem not ours...
