Rangers are basically “the cops” of BLM land, so if there’s an issue they’re the ones who will show up. In general these guys do the best with what they’ve got and they probably hate BM and all the hassle it brings. A normal weekend in rural Nevada requires maybe a call about a rancher’s lost livestock or a normal patrol route. These guys are certainly ill equipped to handle 70k outsiders showing up for a week, and particularly not well equipped for settling interpersonal/ideological disputes elegantly. I think their “ram down the barricade” strategy is pretty parsimonious given the time and tools they have to deal with protests and angry travelers.
