Well the US can do it with CBP/ICE, but not for life. I was placed in a jail without being arrested or being accused of a crime and they were very clear at all times I was not even arrested, nor did a federal criminal history search show any record of arrest. No access to lawyer either.
US Citizen. Contacted lawyers, all informed me they'd given up trying to sue for these things because it's hopeless.
Founding fathers rolling in their graves.
Assuming what you're saying is true, this is the kind of thing 2A was written for. I don't mean for you personally, but for society it's really the last line of defense against a rogue government. But, even if your story is totally made up it's completely believable. Scary times.
You should contact IJ. They recently took up a case like this.
