请问这是谁的错？--Yours. You have the right to

call the police to get that car tolled, but you don't have the right to damage that car, even if it is parked at the wrong spot. Imagine if you parked your car on the street to run into a store to pick up something and later to find out your car got smashed. Would you feel your car deserved it because it was at the wrong spot? You really should just learn your lesson and be more careful next time.... sorry I know you don't like this answer but it is the truth...
