Going forward, the bill departs even more radically from our most fundamental values. It would permit the president to detain indefinitely—even for life—any alien, whether in the United States or abroad, whether a foreign resident or a lawful permanent resident, without any meaningful opportunity for the alien to challenge his detention. The administration would not even need to assert, much less prove, that the alien was an enemy combatant; it would suffice that the alien was “awaiting [a] determination” on that issue. In other words, the bill would tell the millions of legal immigrants living in America, participating in American families, working for American businesses, and paying American taxes, that our government may at any minute pick them up and detain them indefinitely without charge, and without any access to the courts or even to military tribunals, unless and until the government determines that they are not enemy combatants.
