“With a bomb strapped to his chest, one of the Boston Marathon suspects was killed early Friday after he and his accomplice brother robbed a 7-Eleven, shot a police officer to death, carjacked an SUV and hurled explosives in an extraordinary firefight with law enforcement,” NBC News reports. “The second suspect — the one in the white hat in photos released by the FBI — was on the loose. Police ordered people in the Boston suburbs to stay inside and businesses not to open, and began a house-to-house search. Boston shut down its buses and subway system for the hunt.” Might be a good time for area homeowners to be armed (and discreet) no?
