Sergeant, that is.... Some of my favorite sergeants include Sgt. Brady from RIP, Mrs. Columbo; Sgt. Kramer (multiple appearances) and the lovable but very bumbling Sgt. Wilson who as we all know has two first names. Those are my entries!!!
I loved watching Wilson proudly type in Now You See Him. "Very *GOOD* Sgt. Wilson!" And his night-vision camera & footprint in Greenhouse, helping bring the Lt. into the 20th century vis-a-vis technology.
My favourite is Commissioner Mark Halperin.
Also the one played very well by Michael Strong in Negative Reaction.
