Nice strawman, barely anyone is accusing the rank and file of ICE of cruelty, there might be a few bad apples here and there though. But the cruelty is coming from higher up political appointees like Stephen Miller.
USCIS is not ICE. When USCIS refers people to ICE (the topic of this article), ICE has their own procedures which have more to do with carrying out immigration and customs law than "cruelty".
Which results in ridiculous bullshit like this:

Can you tell me how the above situation is not cruel?
