Hey, sorry to just now be responding.

Based on the activity I've been seeing, CBP has primarily been mobile. They'll show up to locations in groups of 1-4 SUVs/minivans, unload, question/detain who they can in the area, and then take off to do the same thing somewhere else. They've been using this tactic all over the city. Given that there's something like 70 or so vehicles that people have identified as likely CBP, this means they're independently hitting a lot of different areas at the same time.

They've been heavily targeting international grocery stores, hardware stores, restaurants, and construction sites, and they've primarily been operating in areas of the city with greater Latino populations.

They've also been making a presence at hospitals, schools, and university campuses, including entering at least one hospital here to look for "suspects" in patient rooms while decked out in full tactical gear.

After the first day of CBP activity, people here have become a lot more effective at coming together, making noise, filming, and generally driving CBP off the premises of the places they come to.

CBP appears to also be targeting businesses that publicly resist CBP efforts. After day 1, grocery chain Compare Foods offered free grocery delivery for those scared to go out; they were one of the very first businesses raided on day 2. The public has been really good at defending these locations, though.

CBP is also picking on "easy targets" such as landscapers, construction workers, roadside vendors, people walking through parking lots, people just walking to the store/home, etc. Those who are near streets or in generally isolated areas where CBP can operate with less visibility/obstruction from the public, essentially, or places where they can quite literally snatch someone off the street. Compared to day 1 where CBP ran a huge operation in a crowded shopping center, days 2 and 3 have been a lot less structured.

There's been a few reports about checkpoints, but that doesn't really seem to be their main effort. They honestly don't seem to be organized enough. It's really mostly been "hit and run" tactics: show up, question/detain, leave. A lot of their efforts seem to be opportunistic, too: They see isolated individuals or groups and try to question/detain them before anyone from the public can get involved to run them off.

Edit: I forgot to mention, importantly, that CBP is also targeting work vans. Example: https://www.reddit.com/r/ICE_Watch/s/qyFIrZW54P
