The US does in fact have customs and immigration laws; are you claiming that those laws were not properly passed, under some kind of anarchist or Sovereign Citizen kind of theory? Or that the State has not charged ICE with enforcement of them?
I think they're saying that while ICE calls themselves law enforcement they're really just (at least acting like) a bunch of thugs. When you give a group this much money and this much power and a bunch of unrealistic goals I can see that happening.
