I think you are maybe approaching this from some rational place with some kind of assumption of good will. ICE on the other hand invaded Hyundai and arrested a bunch of people on various visas without knowing what was law enforcement and what was kidnapping. Big mistake maybe, for who? Met their quota. Only one guy? Can call others as soon as they have found a suspicion and then it is not reasonable to deny other enforcement. It is potentially as illegal as blocking backup to an active crime scene.
