Active Shooter situation currently going on in Washington DC.
I'm a couple miles away in Arlington, but I had a friend in DC say he's seen lines and lines of unmarked and marked Fed. police agencies vehicles heading for the area. Apparently there was a group of undercover "delivery vans" with full lights and sirens passing at one point. News is saying largest police presence in the city since 9/11. Possibly 4 deaths, 10 injured. Witness is saying it may have begun with shooting into cafeteria. Still considered active shooter situation with possible second gunman still on the lose, shots, unknown shooter have been heard in the past 30 minutes.
