Actors who appeared in CSI: Crime Scene Investigation, CSI: Miami, and CSI: NY

In what I call the CSI Trifecta, this is a list of actors that have appeared in all three successful CSI shows. Cyber doesn't count because it got less seasons and sucked, but if they appeared in it I made a note of it.
Someone else made a list like this, but I wanted to focus more on the characters that these actors portrayed.
