And how about the scene with everyone working on the giant touchscreen table monitor. Busy shuffling documents around, and multi-touching them larger and smaller. Over and over and over.

Plus how about when they dump the contents of a camera into one of their fancy computers, and it results in a pile of photographs all on top of each other that they have to then manually separate? Woo, convenient!

Not to mention the impracticality of CSI Miami's big transparent screens. "Is that the killer in the background of that photograph?" "No, that's just Ted coming back from the washroom."

Now, regarding the flashlight use, I've heard it explained that it "forces them to focus on a small area so nothing is missed". Of course you'd maybe want to do that after first going over everything with stadium lighting.
