[Interesting interpretation by someone named Ed Furey]

<begin excerpt>
Beyond repealing habeas
corpus, another grotesque violation of the Constitution is
implicated in that legislation. The Constitution specifically
forbids the passage of a "bill of attainder." In the old
days, when kings and others were not certain they get a judge
or jury to convict someone of a crime, they would simply
declare them guilty (attainted) and imprison, torture and/or
execute them. When Parliaments did this they passed a "bill
of attainder" declaring the person guilty of a crime. What
this recent piece of legislation has done is to declare a
whole class of persons, "unlawful enemy combatants," to be
criminals, subject to punishment -- imprisonment without
trial and torture -- at the discretion of the president. By
the way, this does not exclude American citizens.
