Mediapart's 'À l'air libre' video revisits the 23 October 2026 shooting by Kevin Tessier in Trappes, his supremacist radicalization and shift to the far right, and how he passed under the radar, with the attack per the antiterrorism prosecution leaving one dead, seven wounded, and about thirty victims. Mediapart calls it a racist, anti-Black, and Islamophobic attack targeting people who were Black, Arab, or perceived as Muslim.
