Damn BMW high-pitched car alarm that keeps going off outside my window. What do you want to bet that this continues all night long? I would call the police, but the NYC's policy on car alarms is pretty useless. Basically they will come out and look at the car with a flashlight (presumably to make sure it's not being stolen or whatever) and will do nothing about making it stop or go away. Oh, they might leave a ticket on the windshield or something. If they feel like it. When I lived in Hoboken (NJ) they would tow that car so fast -- it was a beautiful thing.
