Investigating officers: Constable Benton Fraser and Shaft (the newer Shaft, not his Uncle, who I don’t know much about) Fraser is a natural-born tracker (even comes with his own wolf) and Shaft is one bad mutha… but I digress.
Supervising cop: Odo, from Deep Space Nine. He kept a tight space station. Alien invasions, Founder Spies, and Quark’s money-making schemes aside.
CSIs: Either Cain or Grissom from the CSIs, depending on whether or not a child’s parents were killed (Cain seems like more of the guy you need if a kid was wronged somehow) Lt. Commander Data with his Sherlock Holmes hat, and Monk.
Coroner: Quincy, obviously.
District Attourney: Rear Admiral A.J. Chegwidden. He’s just that cool.
Prosecuting Attournies: McCoy from Law and Order and Colonel MacKenzie from JAG (since McCoy does his best work if he has a hot female lawyer helping him, and because Mac can both kick-ass in a firefight and can speak Farsi. That’s gotta come in handy sometime.)
I’d pick Harmon Rabb, except his undeniable skills as a fighter pilot are somewhat limited in scope of application in a city courtroom.
Bonus all-star TV Defense attourney team: Matlock, Captain Picard, and Keanu Reeves from Devil’s Advocate (What? That movie’s been on TV a few times! 
)
