Attorney Carl Messineo is a co-founder of The Partnership for Civil Justice Legal Defense & Education Fund (PCJ-LDEF), which is a sub-unit of the International Action Center, which is a front for the Workers World Party, a Marxist-Leninist "vanguard" which aligns with North Korea. The PCJ-LDEF lawyers also work closely with the pro-Communist National Lawyers Guild. Dedicated to hampering the efforts of law-enforcement officials to investigate terrorist suspects, the PCJ-LDEF has produced a publication entitled "Know Your Rights If The Police Stop You or Come to Your Home," and another titled, "Know Your Rights When the Government, FBI, or INS Calls On You," which is available in English, Arabic, and Farsi. Mr. Messineo is also a member of the legal team defending the anti-war group Voices in the Wilderness, which was fined $20,000 by the U.S. Treasury Department for having illegally brought supplies to Iraq in violation of the UN sanctions that were in place during Saddam Hussein's regime.
