Theoretically? No.

In reality it’s already happening.

This is from ONE concentration camp. If they’re moving people between these ‘detention centers’ and fudging the data or straight up not recording anything on where people are, then they can disappear who they want, and by the time their lawyers or family get visit approval it’s already too late.

We still have a (mostly) free press though. Eventually families and counsel would find out and the news would get it. Unless it started very recently I don’t find this credible.
