What? ICE has admitted the error. The person said to be deported is in an El Salvador prison. The President has said he was deported, and the president of El Salvador has said he was deported. Both have acknowledged this and maintain that it was the right thing to do. Everyone connected with the case, both for and against, seems to agree on the basic fact that he was deported, but you seem to be saying that without specific documentation the entire event is in doubt.
Are you suggesting that he got on a plane and marched into that Salvadoran prison voluntarily? Are you making a semantic argument that sending him out of the country and imprisoning him doesn't count as a "deportation" because the paperwork wasn't filled out? Your continuation of this seems utterly bizarre.
