I can tell you how they behaved at LAX last night.
There were over a hundred of them, in what I'll call mild riot gear (see my photo; I say mild because they weren't wearing ridiculous looking Gundam level shit). They were working in various formations, and made occasional strong movements around and through various crowds. Whether or not it was intended as intimidation, that is the signal it sends. There were a lot of special LAPD vehicles assembled, but again, nothing that really tipped in to the overly military in appearance.
I was actually surprised a bit by how almost soft many of the rank and file officers looked--young, almost gentle even. Neither scared/nervous nor belligerent. In less defensive moments, they were even talking amongst themselves about what was happening, laughing, joking; they looked almost like goofy college kids. Actually, they mostly looked bored.
It was the senior corps of officers that looked like the LAPD I've grown up with and love to hate. Stiff, bitter, uptight looking older men. Also a a whole bunch of suspicious officers with jeans on, bullet proof vests, and cameras. Lots of cameras and surveillance. I'm not sure if this was intended as oversight or something else.
I think one person was arrested, but that person was by accounts very much looking for it.
I'm one of the first people to condemn cops, but in this new war, they are not the primary enemy here. Certainly a group that nees to be kept a really close, tight watch on, but they may, in a sense, become secondary avenues of passive resistance to the horror of this federal government.
Not sure if that helps with some firsthand perspective.
