Muslim-Americans who sued the New York Police Department over a surveillance program launched after 9/11 say calls from the Republican presidential campaign to put them under more scrutiny are recklessly seizing on public fears and distressing Muslims in the U.S.

As national security has become a focus in the 2016 race after the Paris attacks, Donald Trump has declared “we’re being foolish, we’re kidding ourselves” if law enforcement doesn’t keep close surveillance on mosques, and he expressed support for the idea of a database for tracking Muslims in the United States. Another GOP contender, Ben Carson, said mosques, schools, supermarkets, car repair shops and “any place where radicalization is going on” should be monitored.
