Three weeks after the Boston Marathon bombings, some members of Congress are calling for more surveillance of American Muslims. Some Muslims are calling for self-policing of their community and more cooperation with law enforcement. Others warn against accepting collective punishment for bloody violence as abhorrent to Muslims as to other Americans of different faiths. At today's Congressional hearing on the bombings, Republican committee chair Michael McCaul of Texas said the nation had been attacked by "radical Islamist terrorists." New York Republican Peter King echoed that sentiment. We hear a debate about how to increase security without either religious discrimination or an excess of political correctness.
