Haz mat response at Georgetown U.
Cripes, the first home we bought after I got out of the Navy was a condo on Paddington Lane.
The only shooting there was when I went wild turkey hunting legally a half mile west of the development.
Prayers for the cops and other innocents in the area.
This sounds like MS 13 or Mara Salvatrucha. Thanks for helping my old memory.
Every MS 13 thug needs to rounded up and if they resist, shot and killed like a rabid dog. Navy CIS recently had a show based on these thugs in the NV and DC area.
