American Muslims attending a major religious conference in Toronto on Friday are concerned they’ll be subjected to extraordinary searches and delays by U.S. border guards when they return home. Their concern followed a ruling by a New York district judge on Thursday that such searches did not violate the U.S. constitution. Judge William Skretny wrote that Customs and Border Protection “had reason to believe that these conferences would serve as meeting points for terrorists to exchange ideas and documents, co-ordinate operations, and raise funds intended for terrorist activities.” “I believe in religious freedom, and I will not allow the federal government to intimidate me out of that belief,” he said. Last year, several dozen Muslims men and women were searched, fingerprinted, photographed and held for up to six hours before being allowed to cross back into the U.S. after a conference held in Toronto. The New York Civil Liberties Association took up their case. The association sought an injunction to prevent similar inspections following this year’s conference. It also launched a lawsuit demanding the state destroy any personal information retrieved through past searches. The judge did not grant the injunction, and threw out the lawsuit.
