From the Democratic Party platform, as quoted in Reason magazine:
"We will not ship away prisoners in the dead of night to be tortured in far off countries, or detain without trial or charge prisoners who can and should be brought to justice for their crimes, or maintain a network of secret prisons to jail people beyond the reach of the law. We will respect the time-honored principle of habeas corpus, the seven century-old right of individuals to challenge the terms of their own detention that was recently reaffirmed by our Supreme Court. We will close the detention camp in Guantanamo Bay, the location of so many of the worst constitutional abuses in recent years."
http://www.reason.com/convention2008/show/128386.html After Obama's pathetic capitulation on telecom immunity for illegal spying, and the Democrats' token efforts to hold Bush et al. accountable for their crimes, I am deeply skeptical that they'll actually follow through on these promises. But they've got far better odds of doing the right thing than the Republicans.
