When my empty car was broken into in the Short North (because I was parked next to a nicer car which also didn't have anything in it--fuck you coremodels and nakedredhead), I was all excited because the thief had left the window-breaking chisel in the car--probably with latent fingerprints and DNA on it!!
The bored-sounding dispatcher, however, told me that I should just throw it away or keep it, whatever, and that police were never dispatched to investigate car break-ins. Especially when the only items stolen were my ashtray and a ruined Blues Traveler tape.
So basically what I'm saying is that breaking into a car is the perfect crime because nobody at CPD seems to give a shit CPD doesn't have the manpower to investigate. I don't know how much an ashtray and a Blues Traveler tape are worth (FYI car windows will set you back at least $100 if you're insured), but since there's literally no risk of being caught, the risk-reward ratio comes out to something like infinity dollars.
Oh and by the way--I later used the chisel to cut out the throat of a random co-ed up near Cazuela's. Hopefully my car thief was arrested for that.
