The primary restriction on military participation in civilian law enforcement activities is:
....’The Posse Comitatus Act (PCA).21’..
The PCA prohibits the use of the Army and Air Force to execute the domestic laws of the United States except where expressly authorized by the Constitution or Congress. The PCA has been further applied to the Navy and Marine Corps by legislative and administrative supplements. For example, 10 U.S.C. Section 375 directs the Secretary of Defense to promulgate regulations forbidding the direct participation “by a member of the Army, Navy, Air Force, or Marines in a search, seizure, arrest, or other similar activity” during support activities to civilian law enforcement agencies. DOD issued Directive 5525.5, which outlines its policies and procedures for supporting federal, state, and local LEAs. DOD Directive 5525.5 prohibits the following forms of direct assistance: (1) interdiction of a vehicle, vessel, aircraft, or other similar activity; (2) a search or seizure; (3) an arrest, apprehension, stop and frisk, or similar activity; and (4) use of military personnel in the pursuit of individuals, or as undercover agents, informants, investigators, or interrogators. It is generally accepted that the PCA does not apply to the actions of the National Guard when not in federal service.22 As a matter of policy, however National Guard regulations stipulate that its personnel are not, except for exigent circumstances or as otherwise authorized, to participate directly in the arrest or search of suspects or the general public.
So the military can be deployed for ‘support’ services, which mostly would mean various kinds of surveillance or possibly building things. But if soldiers see people trying to get across the border they have to report that to Border Patrol because only Border Patrol can try to stop them.
Here’s another article that states THE Posse Comitatus Act (PCA).21 cannot prevent armed troops on the border....according to the Constitution....
This is bullshit . Ditch the PCA ! To hell with this legal crap . We are being invaded and if we sit here and let lawyers tell us how we can handle that we are not deserving of great nation status .
President Trump should declare marital law in all border states . To include California . The border counties at the very least .
He should also authorize the calling up of a civilian militia of volunteers , apart from the national guards , and authorize them to be deputized as a 2nd echelon screening posse to back up all front line forces .
It’s time to take the gloves off , not quote statutes . Screw the statutes ! Be ready and shoot straight .
