The speech was sponsored by MoveOn.org and the American Constitution Society was webcast, available on some satellite channels, and broadcast on CSPAN.
It was a very good, I think, very important speech: Gore listed so many of the transgressions against citizen's liberties that have been committed in the name of 'safety', flatly condemned the Bush Administration for them, urged that 'enemy combatants' be accorded due process *immediately*, and that the Patriot Act be repealed.
Those are just the high points. Worth reading the transcript or getting a video copy from someone.
