Modern liberals want us to believe that they forgot about that when they wrote the bill of rights. They didn't forget about it when they wrote the parts about unlawful search and seizure, they didn't forget about it when they wrote the other stuff about limits of power and rights of citizens, but they had no idea that people might contemplate taking up arms against an oppressive government.
They must be shocked even now.

I guess I’m just not as easy going as you are. I get irritated when journalists and government drones profess not knowing things every citizen should know. Remember they can get pretty forgetful about constitutional limits to laws and search and seizure when they want to. The Constitution was not intended to be a “living document” but to be set in stone for the life of our Republic.
