Since the late 20th century, the county has been the site of several mass shootings and unusual incidents of gun violence. On October 16, 1991, in what was called the Luby's shooting, disaffected employee George Jo Hennard, Jr., killed 23 people, and wounded 20 others, before killing himself. It was the largest mass murder by firearm in the United States to that time. In 1995, Governor George W. Bush signed a new law easing restrictions on carrying handguns; it allows Texans to carry concealed weapons if they have a permit to do so. Texas overrode a 125-year-old ban on carrying weapons that had been signed and enacted by Governor E.J. Davis. On November 5, in the 2009 Fort Hood shooting, Army Major Nidal Hasan killed 13 people, and wounded 30. He was paralyzed in return fire. He had been described as mentally unstable. On April 2 in the 2014 Fort Hood shooting, Army Specialist Ivan Lopez killed three people and wounded 16.
