Imams, ministers and a rabbi staged a "pray-in" demonstration Monday at Ronald Reagan Washington National Airport and demanded an apology from US Airways for barring six Muslims from a flight last week. The religious leaders demanded an end to racial profiling, saying it was unacceptable in the United States. "These things are troubling to us," said Mahdi Bray, executive director of the Muslim American Society Freedom Foundation. "Driving while black, flying while Muslim, traveling with a Torah or getting with Jesus." Imam Omar Shahin, one of the six detained last Monday at the Minneapolis-St. Paul International Airport in the north-central state of Minnesota, said they had done nothing suspicious.
