Question: The girls try to persuade the police that Liz had sex with a strange man who then killed her. Why then didn't the police do a DNA test and forensics, which would prove that there was no semen in Liz's body, and so show the girls were lying?
Chosen answer: I believe the idea was to take the DNA from Marilyn Manson out of Courtney and put it into Liz's corpse.
Question: The whole point of the trick is to persuade the police that Liz was murdered after having sex with a random stranger. The police decide to accept this suggestion. Why do they accept this, when they know that a woman pretending to be Liz's mother called the school to say Liz wouldn't come in - ie. the police know that a woman must have been involved, yet they decide it was just a man who did it?
Answer: They have no reason to follow up the call or never did all they know is that she was at home.
Question: The song playing during the opening titles is "Volcano Girls" by Veruca Salt. The song seemed to "shape the film", but wasn't on the soundtrack. Why?
Answer: The band had recently broken up when Jawbreaker was released, so maybe that had something to do with it. Or maybe just a good old-fashioned disagreement about how much VS would be paid for using their song? I agree, the soundtrack seemed somehow empty without it.
Question: Maybe I missed something but why didn't Julie go to the police anyway? They might've believed her. The other thing is, once revealed just what sort of sentence do you think Courtney would receive? Maybe a year in juvie followed by several years in state prison?
Answer: It's a common trope in movies and TV shows that when someone unintentionally kills somebody, the person panics and can't think straight. The movie "I Know What You Did Last Summer" is a good example. Since the girls were scared of what they did, they were most likely afraid they wouldn't be believed that it was an accident. As for Courtney, her sentence depends on not only what state the death occurred in, but it also depends on the circumstances of Liz's murder; i.e. was it intentional? Was it an accident? Was there intent? After that, how many months in juvie and then state prison would be determined by again, the state it happened in and the circumstances behind the death.
Question: Since they are all friends why did Julie get mad at Courtney when it was just a accident that she swallowed the jawbreaker? Then when Courtney came out with a plan to keep everyone from going to jail Julie stabbed her in the back.
Answer: Because Courtney killed her she intended for her to suffocate because she wanted to be queen.
Answer: Probably not, but if Courtney did tell the police everything and they questioned Julie and Fern, chances are that both girls would deny all of it.
