Godwin's law exists especially for morons like you. Has anyone here been forcibly removed from their home, their friends, and their family, stuffed into a boxcar, shipped to a concentration camp to starve for a while before being used for medical research or shot or gassed?
Not yet. But don't think it could never happen, exactly that has happened in other countries in the past. The US government has built concentration camps all over the country. They are currently staffed and look ready to be used right now but no-one ever got an answer on why they were built or who they are intended to hold. These places are not part of the prison system but something else entirely.
If you want to scare the hell out of yourself google "FEMA concentration camps". You likely won't believe a word of it so drive out there and look at the inward facing barbed wire and the train systems for mass transport for yourself.
