All U.S. military and federal public servants take an oath to support and defend the constitution. When those same public servants follow instructions from their supervisors (or commanders) to actually violate the constitution, they break that oath.
Arresting American citizens engaging in the constitutionally-protected right to assemble and air their grievance is a violation of that oath. In the same way that Biden has put Putin on notice that will be held accountable and face sanctions for illegally interfering with American politics, he should let the anonymous stormtroopers they will similarly be held accountable for their illegal interference with American politics.
Biden should tell these Oath Breakers that their oath sets up a legal obligation to disobey unconstitutional orders. He should tell them that any punishment for disobeying illegal orders will be reversed if he wins, Those who obey illegal orders will be tracked and either be disciplined at work or face criminal charges
The young men and women dressed in camo on American streets need to pick a side.
