DID former Attorney General Michael Mukasey, former New York Mayor Rudolph Giuliani, Tom Ridge, a former homeland security secretary, and Frances Townsend, a former national security adviser, all commit a federal crime last month in Paris when they spoke in support of the Mujahedeen Khalq at a conference organized by the Iranian opposition group’s advocates? Free speech, right? Not necessarily.

The problem is that the United States government has labeled the Mujahedeen Khalq a “foreign terrorist organization,” making it a crime to provide it, directly or indirectly, with any material support. And, according to the Justice Department under Mr. Mukasey himself, as well as under the current attorney general, Eric Holder, material support includes not only cash and other tangible aid, but also speech coordinated with a “foreign terrorist organization” for its benefit. It is therefore a felony, the government has argued, to file an amicus brief on behalf of a “terrorist” group, to engage in public advocacy to challenge a group’s “terrorist” designation or even to encourage peaceful avenues for redress of grievances.

Don’t get me wrong. I believe Mr. Mukasey and his compatriots had every right to say what they did. Indeed, I argued just that in the Supreme Court, on behalf of the Los Angeles-based Humanitarian Law Project, which fought for more than a decade in American courts for its right to teach the Kurdistan Workers’ Party in Turkey how to bring human rights claims before the United Nations, and to assist them in peace overtures to the Turkish government.
