Article IV Section 4: Protection Against Domestic Violence
Some are rightfully upset at the Constitutional destruction.
Some have mentioned violence. This is inappropriate.
Article IV Section 4 allows government officials to request assistance to suppress domestic insurrections.
It is a secondary matter whether state officials refuse to suppress domestic violence.
Encourage your friends who are discussing violence to channel their energy into identifying illegal US Federal Government operations, and working with state officials to lawfully end all state-level cooperation with illegal US government efforts.
