Making his television debut with an appearance on Beverly Hills, 90210 in 1990, Emmett generally plays the role of a nameless police officer. His association with this type of role began with his appearance in a 1991 episode of the science fiction series Quantum Leap, starring Scott Bakula and Dean Stockwell and also guest-starring Frank Novak and Heidi Swedberg. He went on to play a policeman on such programs as The John Larroquette Show, Melrose Place, and The Guardian (starring Raphael Sbarge, in an episode with Lawrence Pressman). More recently, he appeared as a police detective in the "Hired Guns" episode of Boston Legal, a series starring William Shatner and Rene Auberjonois.

He was also seen in an episode of Brannon Braga's short-lived CBS series Threshold, starring Brent Spiner and also guest-starring Scott MacDonald. He even had a recurring role on the short-lived series City of Angels, during which he worked with Fran Bennett, Robert Foxworth, Dakin Matthews, Tony Plana, Ron Taylor, and Rick Worthy.
