"ICE's human rights abuses"
No-one's saying they shouldn't exist, nor that the laws shouldn't exist (except perhaps with changes). What's at issue is whether ICE is itself breaking the law in enforcing other laws. No-one doubts the need for police either - but it doesn't mean they were entitled to kick hell out of Rodney King.
"That's something no other country I can think of gives you."
Every country in the world has some process for claiming asylum, and all Western democracies I'm aware of have a process of appeal which involves the courts. In Europe we have the European Court of Human Rights which can rule against a country trying to expel an asylum applicant, and has done repeatedly.
