Sounds like some lower-level ICE agents screwed up, and let the subject get away, and they're trying to redirect blame to the judge. I doubt this will stick, barring any new info on what happened.
Looks like I was wrong. For some reason I wasn't aware the that judge smuggled the subject out through the back door that goes through the judge's chambers, which typically judges avoid allowing the general public into, because it implies improper fraternization between a judge and someone involved in court cases.
