Other mistake: Just after they arrest the Janitor, they are walking out of the building past the employee's. The girl sitting at her chair is not actually typing on her keyboard, her fingers never even press on the keys and her screen-saver is displayed on the screen.
Other mistake: Stokes tells "Michaelangelo" he is looking for a blue Honda, blue rims, blue tint. The picture Michaelangelo shows Stokes and Willows is an Acura RSX, not a blue Honda. (Note: The red Honda that the victim was driving is not the one that Stokes is looking for.) Just because the two car brands are owned by the same parent company does not mean that they are interchangeable when describing them. You certainly couldn't call a Cadillac a GM and not be considered wrong even though they are both made by the same parent company (GM).
