I can't remember now what pointed me to this video, but it's on reason.tv. Here's the description:
Fox News legal analyst Judge Andrew Napolitano is among the fiercest defenders of individual rights. Both in his daily appearances on the country's most-watched cable news network and in a series of books (most recently, A Nation of Sheep), Napolitano consistently and defiantly argues that the only legitimate government is that which respects its citizens rights in all cases.
In late October, Napolitano gave the keynote address at the conference Reason in DC, where he delivered a spellbinding speech that blended a masterful understanding of American history with a blazing outrage at the excesses of the new security state. "Who [is] the greatest violator of the Constitution?" asks Napolitano. "George W. Bush has shown less fidelity to the Constitution than any president since Abraham Lincoln."
There's a related interview with Judge Napolitano at Reason Magazine as well.
