Corrected entry: The police conclude as that no money was taken, "no crime was committed." However, armed robbery is still a crime, even if nothing is taken. So is taking hostages and controlling the building illegally for several hours, as well as other subtle misuses of bank property. "No crime was committed" is an unrealistic and unprofessional description of what happened.
Corrected entry: Detective Keith Frazier is told by his superior officer to bury the case because no money was stolen, and no one is pressuring him for answers. However just kidnapping 20-30 people at gunpoint is a very serious crime, and it's hard to see how the victims and the media would just allow the case to be buried.
Corrected entry: All of the hostages are considered suspects because they blend in with the bad guys, as they were all forced to don matching jumpers. The police are told that there is one woman with the criminals and that she has large breasts. So, while questioning one of the female hostage/suspects, the police ask her to unzip her jumper so they can check out how buxom she is. When she unzips her jumper, she is wearing all of her clothes underneath. This should have revealed her as one of the criminals - because the true hostages had been forced at gunpoint to remove their clothes before putting on the jumpers, which surely the true hostages would have communicated to the police.
Corrected entry: The entire premise of the movie rests on the fact that the leader of the gang of "robbers" sole purpose in invading the bank is to gain possession of papers from Christopher Plummer's private safe deposit box. These papers, we learn, reveal his past ties to the Nazis and have been hidden in a safe deposit box which has not appeared in bank records since the building was built. (1) How did the gang become aware of the existence of the papers at all, and (2) how could they have possibly learned where to look for them?
Corrected entry: It's hard to believe that neither a single cop or anyone in the crowd noticed that the foreign "voices" coming from the wire tap was just a recording. It was a single voice, not a conversation, and it had the same pattern, tone, and sound quality (a slight echo) as most recorded speeches.
