Major Nidal Malik Hasan's shooting rampage at a personnel processing center at Fort Hood in Texas killed 13 people and left dozens injured. But it could have been worse if Sergeant Kimberley Munley and Sergeant Mark Todd, two civilian police officers, hadn't stepped in to stop him. The pair, who had been nearby directing traffic, encountered the gunman at the Soldier Readiness Center minutes after Hasan began his attack. Munley, a diminutive cop nicknamed Mighty Mouse who was serving on the base's Special Reaction Team, moved quickly to take him down and was shot in the leg and arm in the ensuing exchange of gunfire. Todd, returning fire, shot Hasan and handcuffed him — bringing an end to the deadliest incident the U.S. military has seen on a domestic base. Hasan, an Army psychologist who opposed the wars in Iraq and Afghanistan, was paralyzed and remains hospitalized; he was charged with 13 counts of premeditated murder and 32 counts of attempted premeditated murder.
