After immigrants are detained by ICE, there are probably records somewhere of who has an attorney, and who is calling family members or an attorney.
For the immigrants who aren’t calling any family or lawyers, the poorest of the poor, people with little to no connection to anyone, who may not even say which country they are from, if the administration were actually trying to kill as many disconnected immigrants as possible in secret, would society know?
For example, if the administration was composed of all types of conservative people, but 30 percent were secretly Nazis or wanted racial genocide, could there be a campaign to not just remove, but kill, immigrants, and the public doesn’t find out?
Yes, in the same way most Germans didn’t seem to know that the SS camps were death camps, it’s very possible – if not probable – that these places are either death camps already, or going to become death camps very soon.
There’s a reason that the administration is so cagey about allowing Democratic politicians in to see the facilities. The other thing is that concentration camps never start as explicit death camps, and the first casualties are always from things like lack of food and disease. Nothing about this suggests any differently.
