These purported
to authorize martial law, the roundup and detention
of people listed on an index
of so-called subversives that was maintained by the FBI,
censorship of the press, warrantless seizures
of property, and the suspension of
habeas corpus by the president, not by the Congress,
as provided in the Constitution, which basically means
that people could be imprisoned without judicial review
