Okay, thank you, I appreciate the answer. And I agree with you that one is a problem, but we live in a world where sometimes errors happen.
The real world answer is that since July, federal judges have found that over 2,300 people have been illegally held and ordered released.
Just for context, this is not counting anybody stopped on the street for some amount of time and then released. This doesn't include anyone who was held and then later released when the government released their error. This is people (a) held indefinitely who (b) managed to get a lawyer, (c) managed to file a habeas petition, (d) the government was allowed to respond, and then (e) a federal judge found the government was illegally holding them. So this is probably a vast undercut of people actually held without legal basis.
I would encourage you to read the court filings in that thread, as there are direct examples where the government fails to give a single reason someone was held, but still opposes their release. There are examples of these petitions being granted daily for people in these Minnesota raids. I would suggest that you pause and consider whether given this mass unlawfulness, you might understand why people are upset and protesting.
