The shooting at the convenience store occurred just before dawn this morning, and the last police officer did not leave the scene until late this afternoon. With all the commotion, no one could have been anywhere within the vicinity of the scene of the shooting and fail to notice it. Jeffrey must have noticed the scene, no matter what he says. He admits that he went to work as usual that morning, and the only way for him to get from his home to his worksite is to go past the convenience store. The main conclusion of the argument is that ['Jeffrey did not go to work this morning', 'Jeffrey was in the vicinity of the shooting when it happened', 'Jeffrey claimed he did not notice the scene this morning', 'Jeffrey noticed the scene of the shooting this morning']
