I am quoting from Garrett Graff, “ICE is eating the Soul of America” in his substack letter Doomsday Scenario:

1) Everything is now ICE.

We’ve [been] watching the Trump administration turn all of federal law enforcement across both the Justice Department and Department of Homeland Security into an faceless quasi-ICE auxiliary, blending all these agencies and agent into some amorphous anonymous blob of masked, brown tactical-vest-wearing federal law enforcement. I wrote recently about how this precisely is what authoritarian regime looks like — armed, masked, anonymous agents of the state jumping from unmarked vehicles and whisking people away

2) Collapse of Moral Legitimacy.

The tactics of immigration enforcement are turning almost comic-villainy evil — take, for instance, the Border Patrol raid on a team of wildland firefighters actively fighting a forest fire. You know how you’re on the wrong side of history? When you’re intervening on the side of helping the forest fire!….When the average blond woman in yoga pants is shouting at federal law enforcement, you know something has changed in the fabric of our country. And there are a lot of those videos too… We are watching the Trump administration burn years and decades of community bridge-building, outreach, and public relations that will make the work of every federal agent in the country harder every single day — and, in turn, make it easier for actual criminals to prey upon Americans.

3) Operating without due regard for civil liberties and due process.

In my essay at the end of August about how America has tipped in fascism, I wrote, “America has become a country where armed officers of the state shout ‘papers please’ on the street at men and women heading home from work, where masked men wrestle to the ground and abduct people without due process into unmarked vehicles, disappearing them into an opaque system where their family members beg for information.”

[After Graff’s post was published the Supreme Court allowed ICE to confront persons without reasonable cause.]

4) Avoiding transparency and accountability.

At every turn….the agency is going out of its way to make it harder to hold officers accountable. ICE officers don’t routinely wear name tags or easily visible badge numbers. Moreover, though, despite the fact that we’re weeks and months into this national ICE takeover, the agency has made no effort to make its masked officers on the streets identifiable to either the public — or even to itself. it’s clear this is an agency that is going out of its way to make it nearly impossible for anyone — including the US government itself — to investigate any official misconduct, abuses, or assaults.
