As a trial attorney for more than 40 years, I'd say these are examples of egregious illegal surveillance of American citizens by the current government:
1. A retired US citizen emailed a DHS attorney urging mercy for an asylum seeker he had read about. Five hours later he received an email from Google advising him the federal government had served Google with a subpoena demanding information about him. Then they followed up by knocking on his door. The federal government's concerted effort to intimidate citizens should concern every American.
2. NYT: https://archive.ph/W5FwO ICE’s New Surveillance State Isn’t Tracking Only Immigrants
A memo from a Department of Homeland Security official reviewed by CNN and sent to agents dispatched to Minneapolis last month asked them to “capture all images, license plates, identifications and general information” on “agitators, protesters, etc. so we can capture it all in one consolidated form.” And the official reportedly provided such a form, called “intel collection.”
3. Moreover, ICE officers have traveled to the homes of protesters. Not to arrest them, because they have done nothing illegal. Rather, ICE was trying to intimidate them by letting them know ICE knows who they are and where they live. https://www.nytimes.com/2026/02/13/us/minneapolis-ice-agents
Egregious, yes. Concerning, yes. Illegal, I’m not so sure. As a fellow attorney, why do you think they are illegal?[1] Maybe they should be, but our jurisprudence since the 1960s (the “put down the dirty hippies” age) seems to treat the the 4th Amendment not as an expansive right to be left alone but as a narrow one that treats only one’s home as a privacy zone.
I found crim pro to be a very distressing and depressing course.
Also, that last link to The NY Times article is broken.
[1] To suggest that the Government doesn’t know what’s legal and what isn’t stretches credulity. They know; and they’re going to ride as close to that line as possible when motivated by their bosses.
