His shock was best captured in his answer to a question posed by reporters:
What I can tell you is that Bush's shock is evidence that he felt that his decision was not only right in a moral sense, but also right with the law. President Bush BELIEVED that the Supreme Court that he and his father and Reagan essentially hand-picked would side with him on this case. Justices Alito, Thomas, and Scalia all sided with the Administration, while new Chief Justice John Roberts was sidelined because of a previous ruling he made as an appeals court judge on this case.
The President has acknowledged that this ruling will not put suspected terrorists out into the World. The bottom line is that the government needs to offer these detainees the opportunity to have transparency in their legal proceedings. Secret military tribunals do not protect us from terrorism. If anything, holding 400 people without officially charging them provides terrorists with more fodder to recruit and incite Muslims for their cause against our country.
Like many of the other facets of the Administration's "War on Terror", keeping things secret does little to make us safer. The Administration wants us to trust that they will make the right decisions about what to do with intelligence and secret information gathered through these programs. Unfortunately, the Bush Administration doesn't have the kind of track record that puts us at ease when it comes to intelligence and handling it. Remember this is the group of bozos that outed a CIA operative working against Al Qaeda, had intelligence about credible threats prior to 9/11 and claimed that it had proof the Iraq had weapons of mass destruction. Forgive me if I want them to be more transparent, since I think information is the safest when their not the only ones with access to it.
