"Meanwhile, Doc Brown was in the process of stringing one final strand of cable between the two lamp posts. As he went merrily about his work on municipal property, a cop meandered over from the Bank of America to watch. / "Oh-oh," Marty whispered as he came out of the cafe. "That's all we need now, is some meddling flatfoot." "
The policeman can also be seen when Marty first walks into Courthouse Square in 1955.
In footage deleted from the finished film, but reinstated for George Gipe's novelization, Doc Brown hands the officer a bribe. The officer asks, "You're not going to set anything on fire this time, are you?" Doc gives it some thought and answers, in the negative, "Naahh."
In more deleted footage, after Marty reads the date on the November 5, 1955 newspaper, he thinks he's dreaming and asks a lady to pinch him. She slaps him instead, and when the officer approaches, Marty hands him the paper and walks over to Lou's Cafe.
