In one scene, the video game Wolfe is playing reflected in a close-up of his eye. Except the reflection isn't a mirror image; the points-message is clearly "1,000" rather than "000,1".
While some violent video games can be quite graphic in content, it is extremely unlikely that a game that rewards rapes of random women would be legally for sale in the US. However, dialog claims that this is true of the game depicted.
In the scene just after the death of "The Wizard" the CSI team goes to a photographers studio, who is taking pictures of a model in undergarments. As the camera rotates, and before anyone speaks, an optical laser point can be seen to the right of the model, sweep across her backside, and sweep off to her left as the camera rotation ends.
Throughout the episode, the characters refer to the university as 'Miami University.' Miami University is in Ohio. The University of Miami is in Miami.
