The identity color reminds me of a recent incident with my bicycle. Somebody chained his bicycle in front of my bicycle, effectively pinning it to the lamp post. After a while I tried asking the police for help, but they were unable to help me, because they would have needed proof that I own the bicycle. Having the keys to the lock (a chain) was no good, because I could have added the chain after the original owner pinned it to the lamp post.
