Isn't this the motte and bailey thing though? "Putting minorities in camps" has the implication that they're being put into camps because they're minorities. It's meant to invoke the thing the 20th century fascists did where if you're a member of the group you go to the camps, and moreover if you go to the camps you never come back.
Meanwhile ICE is detaining people because they're suspected of being in the country illegally, and then deporting them.
They suck at it, as usual, so some of the people aren't actually in the country illegally, but most of them are, and then when the government screws up the courts slowly get around to sorting it out. Which is a process that has maybe been in need of reform for quite a while now -- in particular it would be nice to see the government paying for its mistakes more often, and for the "unscrew this up" process to take less time -- but those aren't novelties only now being introduced, they're longstanding problems.
