Report Details Sources of Confusion During Navy Yard Shooting
Police were hampered at the Washington Navy Yard shooting in September 2013 because a security officer had locked a video surveillance room, which prevented officers from making a clear assessment of the situation, according to a department report released Friday.
As a result, the authorities issued a public warning that an additional shooter could have been involved, and a portion of the city was locked down on September 16, The New York Times reports.
