How many things are wrong in this video? Let me mention at least a few.
1) If guns were still like Muskets the folks in this room would have a pistol or rifle at hand or nearby. Citizens bearing their arms would surround him. They would prevent further action by threat of force or actual force.
2) He would have known the facts in item 1 and would have weighed that against his urge to do violence.
3) Even if the folks in the office did not have firearms, he’d be tackled and restrained in moments. The citizens of the musket-era would not be like roaches running for cover like those depicted here.
In a modern society with the same values as our Musket-Era colonial predecessors, but with modern weapons, the same points above apply. The presence of armed citizens would have prevented any attack or ended one quickly. The first objective would be to put down the shooter using any means available.
Only in a gun-free zone culture over-populated by rabbiting progressive snowflake beta-males, does this video makes any sense. And even then, it makes no sense.
