Hotchner: Garcia, pull up everybody who's signed out a library book in the past 30 days.
Garcia: There's two thousand.
Rossi: How many live in a three-block radius?
Morgan: And drive a green car.
Spencer: The unsub would probably also have a history of littering.
Garcia: Look at that. Just one.

Wow, I could write for that show.
Still, I don't find Criminal Minds as goofy as CSI. Aside from Garcia being able to instantly access and cross-reference information from practically everywhere at once, the technology is not quite as ridiculous.
