Except as provided herein and notwithstanding any other provision of law, including section 2241 of title 28, United States Code, no
court shall have jurisdiction to review, by habeas corpus petition or otherwise, any action taken, administrative proceeding brought,
or determination made --
(1) to detain an alien under section 203 of this Act; without regard to the place of detention, judicial review of the detention of suspected terrorists is available only by habeas corpus petition filed in the United States District Court for the District of Columbia, and only upon issuance of a final order of removal pursuant,to sections 238 or 240 of the Immigration and Nationality Act of 1952; and
(2) to remove an alien under section 201 of this Act; without regard to the place in which the immigration court or other administrative proceedings were conducted, judicial review of an order of removal of an alien terrorist entered under section 238 or 240 of the Immigration and Nationality Act of 1952, and of any cause of claim raised with respect to the proceedings which resulted in such order, is available only by petition for review filed in the United States Court of Appeals for the District of Columbia Circuit, in accordance with the procedures and limitations specified in section 242 of such Immigration and Nationality Act.
In other words (AFAICT), if you're an alien, and somebody in the FBI decides you're, well you're potentially dangerous, you can be locked up, indefinitely, without any judicial review or petition.
And that's the "measured" and "constitutional" response the Administration wants.
May God have mercy on us all (because it doesn't look like anyone in Washington is gonna...).
