Paty showed his students "Charlie Hebdo"'s 2012 cartoons showing Muhammad in a class on freedom of speech. A girl who was not in the class lied about what the teacher taught, and her father made a complaint to the police. He also started the internet "hate campaign" against Paty that caused Anzorov to kill Paty. The murder happened during the trial of other terrorists who were part of the "Charlie Hebdo" shooting in 2015.
