U.S. secretly monitoring radiation levels at Muslim sites in D.C. area

David E. Kaplan of U.S. News & World Report finds the U.S. government has been monitoring more than 100 "Muslim sites in the Washington, D.C., area, including mosques, homes, businesses, and warehouses, plus similar sites in at least five other cities" since 9/11 in search of a terrorist nuclear bomb. As part of the top-secret program, investigators went "on to the property under surveillance, although no search warrants or court orders were ever obtained, according to those with knowledge of the program."
