New York City, San Francisco and Philadelphia filed a federal lawsuit Tuesday, Dec. 26, against the Defense Department, saying many service members who are disqualified from gun ownership weren't reported to the national background check system. A Defense Department failure allowed a disgraced former Air Force member to buy a high-powered rifle and shoot 26 people to death at the church. (Jay Janner/The San Antonio Express-News via AP, File)
