"Foley and Reese picked up the woman [Jennifer] between them — she looked so young, Foley kept wanting to think of her as a girl. She must have spent a bundle at one of those cosmetic factories. And she lived in a place like this [Hilldale]. Foley wondered if there might be something else going on here, the sort of thing that a good police officer should investigate. / But she didn't mention her thoughts to her partner. She already knew what Reese would say. Pure conjecture, Foley. There's no place in police procedure for conjecture. And Foley knew they didn't have time to investigate, either. They were too busy dealing with tranks and Lo-bos."
Bob Gale and Robert Zemeckis generally used the names Reese and Foley in scripts to describe any pair of police officers. In the first draft of Back to the Future, Foley and Reese were two men, officials from the Nuclear Regulatory Commission, who came to arrest "Professor Brown". Other characters named "Foley" were a "theater cop" in I Wanna Hold Your Hand; a Private Foley in 1941 (played by John Candy, with Mickey Rourke as Private Reese); and a character in Used Cars.
