I want to add a running theme in GRRM's A Song of Ice and Fire is that doing gross and inhumane things may horrify us in the moment and make us feel overwhelmed but tends to turn around on those who would resort to such methods despite Tyrion Lannister's opinion that those methods are not to be taken off the table when considering options.

The most well known example in the series was the Red Wedding, the marriage of Edmure Tully, Roslin Frey, which was followed by the massacre of Rob and Catelyn Stark and many others, while under the protection of the tradition of hospitality. If we ignore the GoT Season 8 revenge by Arya Stark (which isn't canon but is based off an implied plot by Lord Manderly), reputation of fell deed figured in House Frey losing allies and trade, and Frey casualties numbered to exceed all its gains and those inflicted on Stark and its allies.

IRL, Trump's heavy-handed response to the George Floyd protests in 2020 only doubled the protest sizes in the following days. Notoriously after Putin-style LGMs (unmarked uniformed men in military gear abducting citizens without due process) and brutal police action at the Portland ICE building resulted in the moms joining the protests and then the dads (who brought their wireless leaf blowers, handy against CS gas).

An example that will be applicable to the US is the rise of the French Résistance during the German occupation of France. Despite efforts by German administrators to advice soldiers to stay polite, they couldn't help themselves and were brutal to the French civilians. The people started engaging in light direct action, tearing down or defacing German propaganda, slashing tires, cutting phone lines, until they found each other and organized. Within two years, they were a formidable fighting force.

Yes, the find out portion of the upcoming era is going to be harsh. People who need services and supplies will not get them. Police will be cruel to folks at the border, and may even hunt down migrants and Trans folks like the SS after Jews. It will be fucking scary, but it will turn bystanders into resistance sympathists, sympathists into activists and activists into militants. And yes, it appears police just can't help themselves but be brutal, and the resistance will not only feel justified in cutting them down, but will eventually hunt them to the ends of the earth to assure they see tribunal, even when the last guard and bureaucrat is ninety.
