Factual error: When the bad guys go though the hidden exit, they're identified at being around 33rd street. They take an elevator up to the Waldorf Astoria kitchen. This is impossible as the Waldorf is on 50th Street.
Factual error: In the street shootout scene, the two bad guys are surrounded by police officers, the police engage them, which created a crossfire situation. Police officers are trained to be aware of what's down range or what's behind the target they are engaging. The shootout wouldn't have occurred in this manner as they were trapped - the officer with the clearest shot would have engaged them. (01:32:00)Snag.1
