I voted for William Petersen. :thumbsup: For me, Grissom is what represets CSI. He was the first and to me the best. I absolutely love Gary Sinise and I think that with Grissom gone, he's number one. But still, William is just like the essense of not only the show but the franchise. I'm not a big fan of David Caruso and though I enjoy Laurence Fishburne, I just don't think he can compare to William and Gary yet.
