Cope with?! These systems and procedures are designed to circumvent the "complex" realities and give cover for deporting citizens and legal residents. So maybe you have a passport, but you've been attending protests, and perhaps even dared to be lippy towards an ICE agent; your passport is going to the shredder, and your ass to Liberia.
I don't know how folk keep assuming DHS/ICE are acting in good faith - a shocking number of people continue to be oblivious until the agents come for them or theirs.
