Upstanding Maryland citizen shoots armed scumbag

And by upstanding, I actually mean an off duty US Capitol Police officer:

The altercation involved an off-duty military police officer and his roommate, Baxter said. The roommate managed to get the MP's handgun and began firing it in a parking lot as the off-duty Capitol officer was driving into the area, Baxter said.

The Capitol officer and the man exchanged gunfire. Both were wounded, as well as the off-duty military police officer, Baxter said.

Good on the cop for doing his duty as a human being by protecting another citizen. I only reflect criticism on the fact that Maryland infringes on the rights of its residents to carry a firearm to protect themselves from similar situations.
