For starters, we learned that the DC police department is CLUELESS.
"WASHINGTON - More than a year after the Navy Yard shootings, the District's police chief is sharing lessons learned from the response and investigation."
She (Police Chief Cathy Lanier) ran MPD's active shooter training at locations around the city for years. While the department had worked with the Navy Yard in the past, she says the department never trained inside the Navy Yard walls.
"We made the mistaken assumption that it's a military base and everyone inside has to be armed," Lanier says.
But only a dozen people were, she says.
