[gryphon]

A man who displayed a loaded weapon at a U.S. Secret Service police booth outside the White House told officers, “I was only going to fire a couple of shots if no one confronted me.”

An officer in the police booth saw Briggs, who was not wearing a shirt, take a holstered semi-automatic .45-caliber handgun from a backpack and attach it to his belt.

The gun was loaded with 13 rounds in the magazine and one in the chamber. A search of Briggs’s backpack found two more magazines filled with 13 rounds and 171 more rounds of .45-caliber, hollow-point ammunition.

But DC's gun laws are so tight that guns instantly vanish as they cross the DC boarder, no?
