Washington, D. C.-Intelligence assessments say that al-Qaeda's weapon of choice in coastal areas is a small boat loaded with explosives. Now, Homeland Security Secretary Michael Chertoff has told leaders of the U.S. recreational industry that it wants America's 80 million boaters to watch for suspicious behavior. Chertoff said states should develop programs for boaters that are similar to neighborhood watch programs and synch them with the U.S. Coast Guard. (MSNBC, Department of Homeland Security)
