Get a badge number!
I got hit by a driver who swerved into the bike lane to avoid another driver this morning. No serious injuries - skinned and swollen knuckles - and no damage to my bike that can't be put right in 5 minutes at home. I was pretty furious, and called the cops - but the cops who showed up refused to take a report, on the grounds that it was an "accident" and they didn't witness it.
Afterward, it occurred to me that it was probably illegal for them to refuse to take a report, which a police officer friend has since confirmed. However, there's nothing I can do about it because I don't have the bad cop's badge number.
So, just a reminder: If you are involved in an accident, be sure that you get not only the driver's plates and licence numbers, but also the names and badge numbers of any cops who come to the scene. You may need them later!
