Question: In Nick's case, why is nothing shown happening to Jackie at the end? I mean, if it wasn't for her kicking out Chase and Andy, so that she could have the house party (while her parents are on vacation), they wouldn't have ended up at the laundromat where Chase dies.
Question: Why is the lighting set so low in the lab? Any lab should be well lit and in government buildings it is normally florescent. How can they see to do any detailed work?
Question: Someone on Reddit said there was an episode where a woman used her son to lure women into entering the sex trade - can anyone ID this episode (not the one with the preacher's wife pimping out her daughters, that was a different one)?
Answer: Maybe "The Lost Girls" (Season 10, Episode 7). It was the last episode of a trilogy crossover with CSI: NY and Miami. https://en.m.wikipedia.org/wiki/CSI:_Trilogy.
Question: Is it really possible to get a fingerprint off the handle of a gun as seen on the show?
Answer: Yes. Fingerprints can be obtained from most places, including the inside of latex gloves. This makes getting a print off a gun child's play.
Unlike the show, finding a fingerprint on a gun handle is rare. Most gun handles have textured surfaces that don't allow fingerprints to form.
Answer: There are not enough jail cells or funding for them to waste time and money charging people for crimes who are an indirect puzzle piece as opposed to being the person who directly committed the crime. While Nick is not a cop, he knows enough about solving crimes to know the law comes down to who is directly responsible. The law doesn't put much focus on who you could put some of the blame on indirectly, hypothetically speaking. No one in law enforcement is going to waste their resources charging Jackie. Particularly when all her lawyers would need to say is, by law, she didn't commit a crime.
