In Bowling for Columbine, logos is used to great effect in a number of scenes. One such scene is when Michael Moore interviews Kmart employees about the store selling guns. The Kmart employees state that they do not sell guns, to which Moore then produces a Kmart catalogue that shows the store sells guns. This use of logos effectively demonstrates to the viewer that Kmart is selling guns, despite the employees' claims to the contrary. Another scene in which logos is used effectively is when Moore interviews the security guard who was on duty the day of the Columbine shooting. The guard states that he did not do anything to stop the shooting, to which Moore then produces a security footage of the guard running away from the school during the shooting. This use of logos effectively demonstrates to the viewer that the security guard did not do his job properly, and that he is therefore partly responsible for the Columbine shooting.
