Is it appropriate to report a stolen item (costs ~ $150) to the police? Full disclosure - this was a jacket stolen at a gym in Silver Spring from the coat rack, but I do wonder about this with respect to items that could be stolen off my bike.

I would certainly handle this as a nonemergency issue. I don't expect my partner will see the jacket returned, but I think that data can matter (and I like to think that they might occasionally drive enforcement).
