Little is known about the July 20th Brigade.  The group has only claimed one attack in its history and that was in December 2002.  All information about this group is derived from this one attack and the letters sent to police stations and newspapers claiming responsibility for the attack. <p><p>Following an attack on a police station in Genoa, Italy, the La Repubblica newspaper received one of these letters claiming the attack in the name of the July 20th Brigade.  July 20th Brigade claims its attack was in protest to several specific and general acts.  First, the group attacked in response to the death of Carlo Giuliani, an anti-globalization protestor at the Group of Eight Summit in Genoa, five months earlier.  The bomb attack occurred one week after Italian courts found the Italian police who killed Giuliani were acting in self-defense.  The second specific act the letter refers to is the shooting death of Fabio Halilovic, a gypsy who was killed in an altercation with police.  Halilovic was traveling in a terrorism hotbed area of Rome known for its anarchist communities.  He was shot after he drove through a police roadblock.    <p><p>The July 20th Brigade also defends it terrorist attack on more general terms.  The letter protests "the torture and systematic violence perpetuated in the streets and police barracks in a vain attempt to repress the people's response against the G-8 summit." (July 20th Letter, Green Anarchy)  In addition, the group pledges its allegiance "to all revolutionaries who are resisting and are continuing to fight in the prisons.  We are avenging our comrades in the struggle." (Anti-Globalization Signature for Rome Bomb, Gian Chiocci)  The reference to prisoners is noteworthy.  Many of the anarchist groups acting in Italy today have professed the same goal, a notably specific objective to help prisoners in Italy and Spain.  Italian terrorism experts believe that the interest in the prisons stems from the imprisonment of several Italian anarchist terrorists active in the early 1990s, which demonstrates July 20th Brigade's allegiance to the Italian anarchists.  In addition, the disparate ambitions of the group combined with a lack of any strategic mission indicates that the July 20th Brigade is simply an anarchist group.
