the rifle was checked out by Capitol Police and the bolt was removed.
As the ATF is so fond of telling us, the rifle is the
receiver, unless the barrel is plugged it is still
considered an active weapon, bolt or no bolt.
Let one of the people do this and see what happens to
them.
Btw, DC PD has zip, zero, nada jurisdiction in the Capitol.
Azz* might try to hang transport issue but even that’s weak.
Bottom line is that it’s political theater
