When Jack first meets Alonzo and his FBI cohorts, he manages to steal Alonzo's badge, which is important to the rest of the movie. However, just as they meet, the other FBI guys grab Jack and then he's in the back seat with them and at no time is he anywhere close enough to Alonzo to take his badge.

Jack tells Eddie to wire $500 to the Western Union office in Amirillo Texas. If the journey started in New York and ends up in Los Angelos via Chicago there would be no reason to go to Texas.
In the scene in which Joe Pantoliano as Eddie Moscone burst back into his office after talking to Jack at Chin Lu's and discovering his phone has been tapped, Joe gets his sleeve caught in the door handle and rips his cuff button off.
