Multiple sources are telling the BBC that a tactical response team ready to respond to Monday’s deadly shooting in Washington, D.C. was ordered to stand down by superiors. The heavily armed team was reportedly one of the first available to aid municipal officers on the scene.

The gunman, 34-year-old Aaron Alexis, went on to kill 12 people at the Washington Navy Yard.

The Capitol Police Department is reportedly pulling radio logs from Monday morning to investigate exactly what happened.

A Capitol Police source familiar with the incident told the BBC: “I don’t think it’s a far stretch to say that some lives may have been saved if we were allowed to intervene.”

The four-man Containment and Emergency Response Team, responsible for guarding the Capitol, were reportedly “wearing full tactical gear and armed with HK-416 assault weapons” when they showed up near the active-shooter situation.
