ICE as an institution is fundamentally evil.

It's using immigration as a pretext to build an unaccountable group of thugs that disappear people into camps, murder political opponents and surveil the populace (as seen in OP). It's recruiting primarily from far-right militias, regularizing them into a paramilitary force of the regime.

There is no justifiable reason to have them terrorize an entire city like they have been doing in Minneapolis.

The brownshirts needed to be abolished in the 1920s, a pinky-swear they wouldn't do the thing they were designed to do wouldn't have been enough.

The same applies to their modern equivalent.
