Just say "oops, sorry, that was a mistake but we can't get that person back" every time you want to disappear someone, and somehow you'll have people claiming that habeas corpus is still alive and well while people get disappeared.
Unless you're Stephen Miller, who insists that no mistake was made: https://bsky.app/profile/atrupar.com/post/3lmrobxubic23
And, more recently, Bukele and Trump insisted that they would not return a "terrorist" to the United States: https://bsky.app/profile/atrupar.com/post/3lmrwrrkbnf2e
It's clear that the administration does not consider collateral damage a bug, but a feature; it confirms that as long as they insist that they will not do anything, then nothing will be done.
Well one thing is for sure: it's not a coincidence that after they determined that it was impossible to get him back, they've changed the narrative to "no mistake was made" (and begun throwing around the magic word "terrorist" which justifies all sorts of things).
> after they determined that it was impossible to get him back
This phrasing buys into the Trump admin's narrative.
They did not determine that it was impossible to get him back. They have chosen to not pursue it. They refuse to define the agreement between the US and El Salvador sufficiently for anyone to know what is or is not possible through that path. They also seem to refuse to use political or financial influence to go beyond whatever that agreement may define.
