Question: A small thing that I was curious about: when Billy and Sidney are in the police station, they are in two rooms/areas that are only separated by a glass wall. In real life, would a suspect be kept so close to the person they are accused of attacking?
Question: What car is Gina driving at the end of the movie?
Answer: A 1966 Ford Galaxie-500 XL. There's a website that lists the vehicles used in the movie.
Answer: No, this is completely incorrect from the film makers. US police stations by law have to have an interrogation cell deliberately so as to avoid the accused person intimidating witnesses or the victim, as billy does to Sydney. Even if the interrogation cell were being used when Billy is brought into the station, he would then be put in a holding cell to wait his turn - they categorically would not just allow him to sit in the public, non guarded part of the station near the accuser.
