During CNN's live coverage of Monday's shooting at the Washington Navy Yard, anchor Carol Costello asked when the last time was that a gunman wreaked "havoc at a U.S. military facility." In 2009, a jihadist killed 13 in a mass-shooting at Fort Hood in Texas.
"I used to work in Washington, live in Washington. This seems so unusual to me that a gunman could create this kind of havoc at a U.S. military facility," Costello stated. "Have you ever heard of it happening before, Brian?" she asked correspondent Brian Todd, reporting live from the vicinity of the shooting. [Video below the break. Audio here.]
