Islamic groups have been relentless in their claims to be victims of discrimination, and it has worked. Since 2011 Mosques have been off limits to FBI agents. See Obama's Snooping Excludes Mosques, Missed Boston Bombers.
However other agencies tried to be less sensitive to outside pressure and stepped in to fill the void. One in particular was the NYPD, which claims that its counter terrorism operations have stopped 14 terrorist plots since 2001.
But now the Islamists are using the courts to pressure the NYPD to back off. See Federal court reviews legality of NYPD Muslim surveillance program. They dusted off some old laws from the hippie days to try to stop the NYPD from investigating anyone unless there is evidence of crimes, and they seek a court appointed observer to oversee NYPD activities.
They claim that their religion is the basis for the scrutiny. But the NYPD says their investigations are based on evidence of legitimate threats, not religion. Meanwhile, those masses of supposedly moderate Muslims are still taking a passive role in all that terrorism business, perhaps waiting to see who ultimately prevails.
