That’s the same as the subpoena I could send you if you had information relevant to a litigation. And you have to give it to me or else go to court to quash the subpoena. But the key difference with judicial warrants is that judicial warrants can be enforced immediately while subpoenas and administrative warrants require the cooperation of the target or else going to court to enforce the subpoena.
Sorry, it's pretty clear that you like what ICE does and you're working backwards with what you think is a legal argument that justifies it. What ICE is reportedly doing has absolutely nothing in common with a lawful subpoena.
I do like ICE, but this point about administrative warrants is a rant I’ve been doing since the Obama administration. The only thing new is that these tactics are now being used for immigration enforcement.
It’s weird but the legal system has an extremely broad view of when third parties can be forced to provide information relevant to litigation. Subpoenas date back to ancient Rome: https://commerciallore.com/2015/06/04/a-brief-history-of-sub...
