Police here would not even turn up for something that small. MIght drive by after a few days and "note' it.
We are only talking a "slap". not cutting the perps hand off or anything.
I had an after market amp stolen from my car years ago. Wasn't noted on insurance so could not claim and police did nothing. I'd still like to find that rat and....I had to clean up the glass and replace the window...just one good slap.
