Every now and then, a car alarm will go off in our apartment complex. Sometimes it's lightning. Sometimes it's nothing at all. Often, the alarm does not shut off, for a very long time. Long enough to enrage me, that's for sure. Despite the fact that the alarm can be heard 3 buildings away, the owner mysteriously never seems to hear the alarm going off.
I hate to call the police over a car alarm, but I would call the police if someone was standing outside my window blaring a bullhorn. I don't think they would respond, or do anything even if they did. I'm not sure if they are allowed to break into a car to turn the alarm off, or if the would do it even if they were.
There are puntive measures (eggs, keys, BBs in the valve caps, sugar) most of which are well-deserved but probably quite illegal and risky.
So, I sit here at 2:45 AM listening to a souped up aftermarket car alarm blare through its 4 unique sound patters, for about 35 minutes now, and there is apparently absolutely nothing that can be done. I could theoretically get cars with loud alarms and just park them outside of people's places that I don't like, and set them off, and there's nothing they could do about it.
