Legal experts examined the document that reveals the following: 

• It provides directives to front-line officers apprehending suspected Tren de Aragua members, suggesting officers obtain a warrant of apprehension and removal “as much as practicable.” Those administrative warrants are signed by immigration officers, not judges like criminal warrants.
• Due to a “dynamic nature of law enforcement procedures” officers are free to "apprehend aliens" based on their “reasonable belief” they meet the definitions, the memo states.
• It purports to grant authority for police to enter a suspected "Alien Enemy’s residence" if “circumstances render it impracticable” to first obtain a warrant.

The memo told law enforcement that immigrants deemed "Alien Enemies" are “not entitled to a hearing, appeal or judicial review.”
