Demonstrably and rather obviously untrue. They're violating the law in many instances, including but not limited to the cases of asylum seekers and current green card holders; it's just they're following the evil, xenophobic whims of the current political leadership, who are failing to hold themselves or ICE accountable to the rule of law, so they are, for the moment, getting away with their lawlessness. I hope we can change this with voting in new leadership, but I fear it may be too late.

Aside and personal observation: it's interesting how the same people so vigorously crying for "law and order" are rather particular about which laws they care about enforcing, and which they're willing to overlook. Of course I'm not the first to make this observation.
