Rittenhouse, clad in a green t-shirt, a cap emblazoned with an American flag, and carrying an assault rifle, was seen on video at various points of the night. In several graphic videos, he’s seen opening fire on protesters; one was shot in the head, another in the chest. The victim who survived was shot in the arm.
While it’s not immediately clear why Rittenhouse, a former police cadet, was at the protest, his social media indicates an affiliation with “Back the Blue,” a pro-police movement. In recent months, pro-cop vigilantes have been showing up heavily armed at protests across the country to defend public property, often warmly received by local law enforcement.
