Janet Ralston should not have been convicted, or even charged with conspiracy in the first degree. New York Penal Code § 105.17 states: A person is guilty of conspiracy in the first degree when, with intent that conduct constituting a class A felony be performed, he, being over eighteen years of age, agrees with one or more persons under sixteen years of age to engage in or cause the performance of such conduct. So in other words Mrs. Ralston's co-conspirator would have to of been under the age of 16, which Gil Himes clearly was not. When both conspirators are over the age of 18 and conspire to commit a class A felony they are guilty of conspiracy in the second degree. First degree conspiracy is a class A-1 felony, whereas conspiracy in the second degree is a class B felony, so there is a pretty large difference when it comes to sentencing.
Detective Logan is shown playing a pinball machine at the bar but the blinking score on the machine indicates the game hasn't been started.
When Sergeant Greevey and Detective Logan are interrogating Willie Tivnan they are still carrying their side-arms, which is a major violation of police procedure. Whenever a police officer goes into an interrogation room with a suspect they are required to leave their guns locked in their desks, this is to prevent the suspect from grabbing a gun from one of their holsters.
