Alexx: What are the odds huh? 100 People throw golf balls at the site of the death.
Horatio: Those odds are very slim, so question becomes, was the mob sent to draw us to the crime scene or to destroy it? (edit) Horatio: You have an ID on him Alexx?
Alexx: No, not yet, I know he died with an empty stomach and a full bladder, strong smell of alcohol.
Horatio: Respiratory failure.
Alexx: Wouldn’t be the first one to drink himself to death. (edit) Det. Salas: I ran those credit cards, looks like Madonna Arias charged $500 dollars worth of gas since yesterday.
Horatio: That’s an interesting ability for a dead woman. (edit) (Eric questions a suspect)
Suspect: “You’re a dead man” is just an expression.
Eric: No, legally it’s a threat. (edit) Calleigh: Do you think the parents have any idea that they’re paying for their kids to have sex with teachers and buy their grades?
Ryan: I don’t know, but it makes me realize what an angel I was.

Goof: The threatening e-mail has two different days of the week in its date header. It reads "Date: Tue, Sun, Oct 3 14:36:14 PST." (edit)

The concept of a flash mob was pioneered in a 1973 short story, Flash Crowd written by science fiction author Larry Niven and included in his 1973 anthology The Flight of the Horse. He further explored the concept in a second, unrelated short story, The Last Days of the Permanent Floating Riot Club, published in the 1974 anthology A Hole in Space.

Niven's flash crowds differed from the mob depicted in this episode in that they were supported by teleportation technology. However, the concept is much the same - a random group of individuals converging on a spontaneously chosen time and place. (edit)
