The Satmar hasidic group illegally sounds air raid sirens every Friday in Williamsburg, Brooklyn to announce the coming Sabbath. And, despite complaints from neighborhood residents, neither the NYPD, the Brooklyn D.A., or the city has stopped Satmar forom doing it.
The description of the above video reads as follows:
There is an Air Raid Siren in Williamsburg that goes off every Friday. They use the Siren for Sabbath. It annoyed Brooklyn residents and tried to take the Siren down by complaining this to the NYC Government. But they couldn't due to this Siren using it as a religious act. More Description coming soon... oh and by the way, the model siren they use is a STH 10 Siren.
Actually, it is illegal to use government property for religious purposes, so if the siren is an official air raid siren, its use by Satmar is illegal.
If the siren is privately owned, it is also illegal because it violates noise and public safety ordinances.
But this is ever-corrupt Brooklyn and ever-corrupt New York State, and when it comes to haredim and their bloc votes, laws do not matter.
