I want to see a squadron of Marines marching in double time up to the city hall to arrest the leaders of this junta. Same in Sacramento.
I think that is necessary for the safety of law enforcement to avoid unnecessary injuries.
I don't want to see regular military enforcing civilian law, which is illegal anyway due to the Posse Comitatus Act. However, there are some exceptions providing Congress authorizes such. I don't believe arresting State or local officials for breaking Fedgov immigration laws would justify Congressional action. Besides, it would take too long and make a mess.
All you really need is armed ICE and Marshall Service if needed for back up, depending on size of the operation/arrests. If the officials call out their Sheriffs to make a fight, then maybe the State National Guard. It would never go that far in Blue jurisdictions that coddle illegals...they don't have the cojones.
The liberal/socialists would probably go willingly to jail and fight it in the courts with a martyr smile on their face. That said, arrest some and make an example of them. Make them spend their own money to drag it through criminal court.
I've read that a couple of them are already backing down because they don't want to lose their share of Fedgov tax dollars returned.
