Revealing mistake: In the final scene, if you look in the background that is completely opposite of the gate where the characters exit, there are two cars obviously made of cardboard. Many times they can be seen by looking over Maria's shoulder. (02:22:05 - 02:25:35)
Revealing mistake: When Maria is cradling the dead Tony you can see Tony's chest heave as the actor takes a breath.
Revealing mistake: In the dance scene, when the two gangs are "battling," if you look in the background at the Sharks side, you can see Maria among others mouthing the rhythms of the songs. (00:37:25)
Answer: Officer Krupke and his partner pulled up in the squad car in front of Doc's earlier that night and asked the Jets why they were all there blocking the sidewalk, then mentioned that he knew they were cooking up something at the dance, and warned that he's coming back. Later, during the war council it's Lieutenant Schrank who shows up at Doc's. So how did Schrank know to show up there? Krupke could've told Schrank something may be going on at Doc's involving the two gangs.
