From what I recall the guy didn’t even have a gun. Only a couple rounds rolling around in a desk drawer.
Some sabots for muzzle loader, can’t be defined as ammo.
One shotgun shell with spent primer that did not fire. Can you call that ammo?
BUT!!! David Gregory exactly violated an explicit law!!!
I don’t care what his (elite, better than the common man) purpose was.
You or I would be in jail (if we weren’t SWATTED dead before that).
