Re other law enforcements protecting him, other law enforcements do seem to be a factor here.
So you have a fed flying squad of thousands of immigration officers, that the admin appear to be using in an aggressive way against dem states.
These immigration officers are, on appearances, cruising about in multiple unmarked trucks, decked out with more guns than soldiers in a war zone, no standard uniform, and their presence and methods are being protested against.
Groups of protestors, share where ICE are spotted and head out to disrupt them. Block the roads, drive a hundred yard further on, repeat.
It seems to me, the usual thing for immigration officers to do when being hindered by protestors, should be to call the regular local Police. They are the ones with full power of the law. They are the ones supposed to know the law, they have marked police cars, uniforms that identify them, the power of arrest for obstruction etc, and local cop shops to process, and hold if required.
But ICE did not have the LEOs for assistance here. I don't know if the LEOs said "nah", the local cop boss/Mayor told them not to assist, or if ICE even asked for assistance.
So a game of cat and mouse ensued between ICE and the protestors, one ICE lost his rag, and appears to have manufactured a scenario where he could shoot dead a demonstrator.
I am surprised the ICE defenders are not blaming local LEO. But that will come soon enough.
ICE should be working with local law, but appear to be working separate to them, against them even. And this does not make sense. Because its LEO who know who the crooks are.
The last bit also explains why ICE are arresting the convicts already in jail, then deporting them, as free people. Because it makes up the numbers, and gets criminal names to post to the press,
Ater all, cruising the street in full combat garb, randomly stopping " brown people", is not intelligence based police work. And I can see how LEO would be pissed off. Possibly months of work on cases being destroyed.
