Are you not an American? (Giving you the benefit of the doubt here)
In America, immigration enforcement is not a criminal issue but a civil issue. So the proper (as in, according to the laws and norms of the last many decades) and appropriate channels through which the enforcement of immigration is meant to be resolved is the courts. The current usage of ICE as a gestapo is literally illegal (it deprives "suspects" of due process and civil/human rights), in violation of Geneva conventions, and so on.
Furthermore even if we accept the blatantly immoral and illegal idea that federal agents should be able to break and enter into homes and kidnap, traumatize, and traffic people without the slightest pretense of legal justfiability (warrants etc), the fact is that they are not even attempting to choose people by any discernable metric other than their skin color. So it is objectively not about the enforcement of the law, it is about stochastic terrorism and ethnic cleansing, as that is the only thing their actions consistently demonstrate.
