Audio problem: When Hooker first meets Gondorff he says "he didn't tell me you were a screw-up." However, when he says 'screw-up' in some versions you can't distinctly see his lips form the letter F, meaning that he actually said another, ruder word that was covered up later.
The Sting (1973)
1 audio problem
Directed by: George Roy Hill
Starring: Robert Redford, Paul Newman, Charles Durning, Robert Shaw, Dana Elcar, Robert Earl Jones
Factual error: When Hooker comes out of the diner there is a billboard advertisement to the right. It is for Ezra Brooks bourbon. Ezra Brooks brand wasn't created until 1957.
Doyle Lonnegan: Not only are you a cheat, you're a gutless cheat, as well.
Trivia: Even though it sets the mood for the film, Scott Joplin's ragtime music was no longer popular during the 1930s.

Chosen answer: Snyder only knew that Erie was friends with Hooker, and he wasn't on Lonnegan's payroll, just a run-of-the-mill corrupt policeman, so he didn't know Erie was involved. The Courier barely saw Erie and so may not have been able to identify him as well as he did Hooker and Luther, so Erie was unknown to Lonnegan.
