This is also blatant misinformation. No judge ever made a finding that he was associated with MS-13. The government asserted it in court but it's never been proven. The immigration proceedings largely revolved around his asylum application, interview, and testimony.
So they're lying in an attempt to make it sensational enough to bust past due process. For an example of how that looks long term, check Duterte's regime in the Philippines. Many people were killed extrajudicially and written off as drug dealers.
