Forensic scientists have almost universally accepted the Locard Exchange
Principle. This doctrine was enunciated early in the 20th Century by Edmund
Locard, the director of the first crime laboratory, in Lyon, France. Locard's
Exchange Principle states that with contact between two items, there will be an
exchange.Goofs:

[Scene: ME's Office.
Lobby. Jordan and Lily walk out of the elevator.]
Jordan: And there's Nigel making these balloon animals
out of somebody's small intestine. (Garret walks past
them.)
Garret: What?
Jordan: Dream.
Lily: Nightmare.
Lily: Are they getting back together?
Jordan: At 9am on a Tuesday?
Lily: He’s wearing a tie she gave him.
Jordan: Maybe he just likes it. Lily. You aren’t
still…smitten with Garret are you?
Lily: No, but Rene Walcott is.
Jordan: Ah…I wish her good luck. I mean having another
man’s child while seeing Garret…who is a little old
fashion.
Lily: Still he’s wearing that tie.
Jordan: I want this guy. I want his head on a tray.
Lily’s mother: Gruff. Mysterious. Just like your father.
Lily: Which one?
Parker: You’re both dark haired. All the victims were
dark haired
Walcott: Is that a threat?
Parker: If I had killed those women…
Jordan: Is there more?
Parker: It would have been because they had evil in
their eyes. Like you.
Matt: How are you doing?
Lily: I don’t know. Car slams into your mother right
after you call her a slut, how would you feel?
Matt: This woman waited for your mother to come out
then... smack.
Lily: You have the sensitivity of a lizard.
Woody: (hand up) Excuse me, but my witness is not
nothing.
Woody: (to Jordan) I saw the way that bleep was looking
at you. Until that guy goes down I'm gonna be on you
like feathers on tar, wherever you go.
Woody: (to Jordan and Walcott) You two are so much alike
it’s scary… (look of disbelief from Jordan and Walcott)
Anyone gets between you and what you want…I’m just
saying…
Woody: Jordan. You are coming with me.
Jordan: No… I’m probably safer here.
Woody: You are not arguing. Come on.
Walcott: A high heel in the shin is apparently somewhat
disabling.
