Well then since federal agencies are now abusing this letter of the law in complete bad faith and disrupting the general peace, it sounds like it is up to state governors to tackle this epidemic of masked gangs of thugs running around and abducting people - order their law enforcement to interrupt any and all masked gang activity and arrest the perps (and order their national guards to deploy if additional force projection is necessary to restore law and order). If it turns out a given gang was acting under "legally valid" federal authority to carry out "legally valid" federal actions and therefore has immunity (and wasn't say a drug cartel hit squad emboldened by the general disorder), that can be sorted out and verified through due process in the courts. States owe no less to their citizens.
