On 14 July 2002, 25-year-old Brunerie attempted to assassinate French president Jacques Chirac by firearm during the Bastille Day parade on the Champs-Élysées. The week before the attempt, Brunerie obtained a.22 Rifle. On the day before the attempt, Brunerie left a message on the Combat 18guestbook saying "Watch the Tv This Sunday, i will be the star... Death to zog,88!" Armed with a.22 rifle hidden in a guitar case, Brunerie attempted to fire one shot from the sidewalk at the passing presidential motorcade before spectators noticed Brunerie. Brunerie then attempted suicide but spectators were able to divert his gun before the police were able to arrest him. According to police, the shot was very wide and the shooter's inexperience and lack of preparation made unlikely a successful assassination attempt. Brunerie was found to have been linked to the far-right group Unité Radicale, and had been a candidate for the far-right partyMouvement National Républicain at a local election, as well as being associated with the French and European Nationalist Party. After the police searched his house, they found a copy of Mein Kampf and a skinhead-themed music CD. Brunerie's trial began on 6 December 2004. The court eventually found the defendant guilty of attempted murder, judging that his mental responsibility, though diminished, was not abolished. On 10 December 2004, Brunerie was sentenced to ten years of prison. He was freed after seven years in jail, on 3 August 2009.
