What to Watch on Tuesday: A wedding (finally) on 'Parenthood'

NCIS (8pm, CBS) - A chief petty officer is murdered and the investigation reveals that his death is linked to an international arms dealer, which jeopardizes top-secret clearance at a Naval laboratory.

Switched at Birth (8pm, ABC Family) - Daphne is unsure about her romance with Wilke. Meanwhile, Emmett isn't happy to learn that Bay is still in contact with Ty.

Parenthood (10pm, NBC) - In the finale of what has been a pretty strong third season, the family gathers for the wedding of Crosby and Jasmine (I'm just so glad all the bickering between those two is over!). Meanwhile, Julia and Joel try to recover from the stress of the adoption process, Crosby and Adam come to an agreement about whether or not to sell the Luncheonette and Sarah makes a big decision about her future.

Southland (10pm, TNT) - Tang is served legal papers in the morning and is involved in a shooting in the evening, and Lydia comes to a decision about how to deal with her pregnancy.

Justified (10pm, FX) - Raylan's tactics put him at odds with the FBI as he intensifies his efforts to take down Quarles and the Detroit mob.

The Amish (2am, UNC-TV) -  Filmed over the course of a year, this American Experience documentary seeks to answer questions about the insular religious community of the Amish. Filmmakers received unprecedented access to the Amish community and it's said to be the first film to deeply penetrate the profoundly private group. It also includes the first television interview with one of the parents of a schoolgirl murdered by Charles Roberts in 2006. As for why this is airing at 2 am while concert repeats air earlier, all I can say is ... Festival.
