Projectile Motion - The science that deals with the motion, behavior, and effect of projectiles.
Tipping Point - A sociological term used to describe when something unique becomes common. Reversion to the Mean - A statistical concept that numbers will average out over time.
The movie being shown at the theater at which victim number five is shot is Sorry, Wrong Number.
Terry was once married.
When Don and Alan are eating lunch, the position of their water bottles change several times, though they never touch them .
In the scene where Charlie and Amita talk about the corrupt data not being corrupt, Charlie draws a pair of axes. He then labels the horizontal axis "Y", when the horizontal axis is supposed to be labeled "X", and the vertical "Y".
When Sinclair looks at the body of the mailman, Sinclair says the victim was shot with a single gunshot wound to the chest. Yet it's clear that he had his back to the sniper, and was walking away when he is shot, so it should have been a shot to the back.
The clothing and equipment worn by the letter carrier killed by the sniper used the old U.S. Postal Service logo, which has not been used for years. The logo appears on the carrier's jacket and mail sack.
With everyone clearing the street, why would Sinclair be standing out in the open just talking on a phone? Wouldn't he be looking for cover?
The area where victim number five is shot does not match the area where Charlie and Edgerton come out. Also, why would David and Terry need to get out of a car when they're only a few hundred feet away? One can see this scene was filmed later in the day by looking at the sunlight on the area.
If Wayne Osborne were really planning on shooting just the postman, why did he bother pointing at the woman and her child? Wouldn't he be looking for his specific target instead of looking like he's trying to choose?
David: Reminds me of snow days back home. School shuts down. Everybody stays home.
Terry: Except nobody is having any fun.
Terry: Called my ex-husband this morning.
Terry: Yeah. No real reason. The thought just occurred to me, what if I never got another chance to talk to him?
David: How did that go?
Terry: We got in a fight.
Edgerton: It's my job to put my head inside the mind of a killer. Your brother's, too.
Charlie: Exposure to actual events helps my statistical model.
Alan: It's the exposure that I'm worried about. Come on, there's a crazy guy out there still shooting people.
Larry: Children are wormholes.
Larry: Yeah, they're portals into the unreachable future and unattainable past. No, as things stand now they exist only in the theoretical realm.
Amita: Well, I could see why you might have some trouble selling a woman on the idea of carrying your wormhole.
Charlie: I am an exceptional basketball player.
(He tosses a wadded up paper towards the wastebasket and misses.)
Charlie: But let's say for the sake of this argument that I'm, that I'm not.
Don: Yeah, I think I could argue that side a little better, Charlie.
Charlie: Tell your aunt that statistically she's more likely to be mauled by a bear.
Larry: Actually, statistics favor the bear being mauled by my aunt.
Don: Not bad. A great deal of beginner's luck there.
Charlie: Beginner's luck is not empiric. It's counter-intuitive.
Don: Yeah? First time I golfed, I parred four on the first nine.
Charlie: That's just a function of regression to the mean.
Don: Anything else?
Edgerton: Yeah, he's going to do it again.
Charlie: How do you know that?
Edgerton: The thing about snipers... we love it. And that's not a guess either, that's a fact.
