Watch it

“30 for 30” (8 p.m., ESPN). “One Night in Vegas,” examining rapper Tupac Shakur’s 1996 slaying in Las Vegas hours after attending a Mike Tyson fight, and the friendship that existed between Shakur and Tyson.

“White Collar” (9 p.m., USA). It’s the mid-season finale, as Peter and Neal make progress tracking down Kate’s killer.

“Sons of Anarchy” (10 p.m., FX). Season premiere. The baddest biker gang on TV is back for another season. SAMCRO is gunning for the rogue IRA guy who kidnapped Jax’s son, and Gemma’s on the lam, framed for murder. It’s not a show for everyone, but if you can handle grit and violence, it’s one of the best series around. DVR heads up: This will run an odd 73 minutes.

“Louie” (11:13 and 11:44 p.m., FX). The last two episodes of the season. In the first one, Louie tries to get into shape. In the finale, he goes out for the evening. Awkward hilarity ensues. And note the odd starting times.

Record it

“My Trip to al-Qaida” (9 p.m., HBO). A hybrid film combining Lawrence Wright’s one-man play about terrorism with documentary footage of Wright’s investigation into the roots of al-Qaida. Might be eye-opening, sure to be at least thought-provoking.

“Warehouse 13” (9 p.m., Syfy). Pete and Myka use H.G. Wells’ time machine to travel back to 1961 to stop a killer.

“Chopped” (10 p.m., Food Network). Part 2 of the past champions’ tournament. Tonight’s ingredients include catfish and alligator.

“Covert Affairs” (10 p.m. USA). Annie has to bring an Iranian dissident in from the cold. (Do spies still do that now that the Cold War is over? Bring other spies in from the cold, I mean? Either way, it sounds cool, no pun intended.)

Skip it

“Wipeout” (8 p.m., ABC). Sorry, summer’s over.
