I hope to see the day the perpetrators will punished.

This is unfortunately incredibly unlikely, at least when it comes to the people who are really responsible.

Some of the foot soldiers working in these prisons might get some punishment assuming we in the US still live in a functioning democracy (IMO until after the midterms happen, this is actually an open question) and if power is able to shift away from the current administration, but the people really responsible for this are above federal law, which is a thing we allow in the US.

They will all be mass pardoned by Trump before he leaves office.
