Mass resistance movements tend to come at unpredictable moments. The killing or particularly well documented crime of a government, for example. Something acute will trigger it, like George Floyd or Renee Good (whose murder triggered widespread outrage, protests, and despite the bots on Twitter, some shift in the view on ICE from the middle and right).
If, for example, a brigade of soldiers or officers opened live fire on protesters, I think the country would shut down.
Another point, as others have mentioned: It's actually the massive amount of armament on both side of the equation that keeps people from taking the next step. The citizens of Minneapolis could probably take out a hundred ICE agents a day, but now we're in a civil war because the next steps are insurrection act, hundreds of people dead in days, potential of the MN state guard being activated to fight against national forces, and it's already three steps ahead of whatever would happen in Spain.
edit: There are some people already exercising their rights loudly. See: https://old.reddit.com/r/LateStageCapitalism/comments/1qdnmh...
That is not a civil war.

The local and federal authorities are at a complete standoff right now. When's the last time you recall a local government essentially asking the court for permission to deploy its national guard to enforce a restraining order against the federal government? All while said federal government was openly conducting sloppy pseudo-urban-warfare in broad daylight?
I urge you to pay attention.
Won't happen.
And it's not that "the administration as a whole" wants devastation, but study up on what Stephen Miller wants.
