'Active shooter' report at military base was false alarm

JOINT BASE ANDREWS, Md. (AP) — A report of an "active shooter" at a military base outside Washington where the presidential plane Air Force One is stationed turned out to be a false alarm, though it locked down the base for more than an hour.

The report stemmed from someone who made a distress call after seeing security forces doing a routine inspection Thursday.

The president, vice president and other senior government officials fly in and out of Joint Base Andrews.

Chris Grollneck, an active-shooter prevention consultant who has worked on training at Army and Air Force bases, said the response to the report at Andrews was well-orchestrated and shows how much the military's training for active-shooter situations has improved.
