Holding
The Ninth Circuit’s judgments—that respondents, who are deportable for certain specified crimes, are not subject to 8 U. S. C. §1226(c)(2)’s mandatory-detention requirement because they were not arrested by immigration officials as soon as they were released from jail—are reversed, and the cases are remanded.
