Description: Reasonable Doubts is primarily about the working relationship between Assistant District Attorney Tess Kaufman, a prosecutor very sensitive to the rights of the accused, and hard-charging, gruff Detective Dicky Cobb, an old-fashioned cop with a "bust-the-perps" attitude. The reason that these two are assigned to work together was that Cobb is one of the few available police officers who knows sign language, and Tess, like the actress who portrayed her, is deaf.
