I would advocate for a legal solution to the government, some kind of limited form of amnesty based on the work they have contributed. I do believe there were too many people that entered the country during Biden's presidency and they need to go back to the border - but allow them to re-apply legally and have better tracking of where those immigrants are staying.

Do you think any Americans (as immigrants) in other countries don't have their addresses in database or two?

As with many matters of importance, I don't see individual and small-scale tech solutions helping a lot. The "new deep state" has way too many resources and tools, including the DOGE and Palantir data collection operations.

Existing organizations, such as ACLU [0] are on the front lines, though their tech is probably focused on the legal system.

And as far as influencing legislators, social media and no doubt phones and emails are flooded by bots.

IMO, this matter is extremely difficult, since it is the focal point both of rabble-rousing and of turning law enforcement into an anonymous, unbadged and un-warranted extralegal state police force. Group action seems the only answer to me.

I recall that California is considering legislation to ban masked agents. I believe that masked faces can be de-anonymized, as evidenced by Apple FaceID, and by attacks on phone cameras and their users.

I gave a lot of thought to ways that technology can improve life in general, but they all ended up undoing what technology has done in greedy or authoritarian hands.

I haven't given up.

Some people were giving out MAGA hats to immigrants to throw a little sand in the gearbox.
