> we are seeing time and time again that ICE/DHS agents are finding the wrong people

There is a difference between what you are seeing and what is actually happening.

99.9% of the time they are finding the right people, but "illegal alien was deported" is as interesting a news story as "water is wet".

They are going door to door in the neighborhood I grew up in.

They're bringing in a lot of US citizens here in Minneapolis/St Paul, including a bunch of Native folks.

The sex offender they'd been looking for at ChongLy Thao's house had already been in jail for a year.

The Dept of Corrections is annoyed enough about the slander of their work that they now have a whole page with stats and details about their transfers to ICE, including some video of them transferring criminals into ICE custody https://mn.gov/doc/about/news/combatting-dhs-misinformation/

I am pretty nervous about the possibilities for trampling peoples' Constitutional rights in ever more sophisticated ways, but the current iteration can't even merge a database and then get accurate names & addresses out to field agents. (That doesn't stop the kidnappings, it just makes it a big waste of money as adult US citizens with no criminal record do by & large get released.)

The evidence goes strongly against your claims.
