 Three years later, in September 2014, Carol D. Leonnig from the The Washington Post released an investigative report describing the details of the Secret Service's "bungled" response following the shooting. The Secret Service responded to the criticism, stating that the shots were fired from a quarter-mile away, resulting in echoes obfuscating their origin, and that initial witness accounts stated that the shots were fired at another vehicle from a black vehicle. An agent who asked to remain anonymous stated, "I'm not saying this was our shining moment, but we never stopped looking for [the gunman]." A former agent stated that the Secret Service needed to change its ways in order to prevent "complacency" and stop future attacks. As a direct result of the attack, additional security measures, such as personnel changes and physical improvements including additional surveillance cameras, were implemented at the White House. It was the first shooting at the White House since Francisco Martin Duran's fired shots at President Bill Clinton from the fence overlooking the north lawn on October 29, 1994.
