I noticed in the trailers on TNT Buzz Watson has a badge on his belt that looks like the badge L.A.P.D. officers wear. It looks very much like the ones worn on the belt of the male cast members when you see them walking towards the camera.
During his time on "The Closer" Buzz Watson has never had a officer size / style badge, but instead an ID card on a clip.
Update: I noticed in the next to last episode of "The Closer" (Armed Response) Buzz has this badge already on his belt. I just don't remember him getting a badge during an episode of "The Closer." Can someone point me to it and where in the episode, please?
