Roving Presidents apparently alter a location's legal status.

Ok smart guy, what if the bullets used to shoot at the president from state territory were covered with some sort of ablative-state material...so even after entering the presidential force field they were still state weapons?  Who gets jurisdiction then, huh?

Do the bullets get covered with that ablative-state material, or just the gun?

What if some of those nuts carried mortars that had enough range to go from state to federal territory?

They are carrying weapons that are legal to carry within the jurisdiction they are carrying them. I suspect there would be plenty of reason to intervene if people started toting around mortars or RPGs because that would not be kosher whether the President was nearby or not.

Actually, mortars are kosher; RPGs are trayf.
