Stryker Brigade Patrols For Insurgents in IraqThe latest episode of “Frontline” (PBS, 10 p.m., check local listings) begins at the premiere of “Zero Dark Thirty,” the Hollywood hit that purported the inside story of the killing of Osama bin Laden. The movie’s supposedly inside details were provided by the CIA, bent on keeping up the illusion that its “enhanced interrogations” led to the killing.

Actually, the techniques of torture were not only illegal by Geneva or any moral standards, they didn’t work. But that wasn’t known until details were told in a massive torture report finally released in December after much effort to suppress it. Tonight’s important report by Michael Kirk, “Secrets, Politics and Torture,” is perhaps the most succinct — and hence shocking — report of how your government became one that tortures, denies it, and  scrambles to cover it up.

A winner is named on both “Dancing with the Stars” (ABC, 9 p.m.) where Patti LaBelle, Sia and Jason Derulo will also perform; and “The Voice” (NBC, 9 p.m.), where other performers will be Maroon 5, Kelly Clarkson, John Fogerty, Meghan Trainor, Luke Bryan and Ed Sheehan. A fifth hour of “The Voice” this week comes at 8 p.m. with a recap.

Also reaching its first season finale tonight is “The Flash” (The CW, 8 p.m.).

It’s unusual when one network pauses to report on the changing of an era at another, but here’s “CNN Special Report: David Letterman Says Goodnight” (CNN, 9 p.m.), hosted by Jake Tapper, the night before he bids farewell. By the way tonight’s penultimate “Late Show with David Letterman” (CBS, 11:35) ought to be a great one, with Bill Murray making his 44th and final appearance and Bob Dylan making just his third, yet his first in 22 years.

I had forgotten quite how simple-minded, slow-moving, repetitive and pocked with unnecessary confessionals “The Bachelorette” (ABC, 8 p.m.) can be. But now, in part two (!) of the premiere, we see which of the two unfortunate women will proceed as Bachelorette and which will be humiliated on national TV for the second straight season. And now, even the drunk suitor is gone.

Fox seems to be eating up its prime time two episodes at a time, so here’s two episodes of “Hell’s Kitchen” (Fox, 8 p.m.).

What’s Ricky Schroder doing in Afghanistan? He’s embedded with U.S. military units there for the new docuseries “The Fighting Season” (DirecTV, streaming).

Amy plays an overaged entrant into a child beauty pageant on a new “Inside Amy Schumer” (Comedy Central, 10:30 p.m.).

Polar bears invade Churchill, Canada on “Deadly After Dark” (Animal Planet, 8 p.m.).

Liza visits her old book club on “Younger” (TV Land, 9 p.m.).

Journalists are being murdered everywhere, even on “iZombie” (The CW, 9 p.m.).

A big paintball fight ensues on the latest episode of “Community” (Yahoo Screen, streaming).

Turner Classic Movies surveys some work by Robert Benton, who wrote “Bonnie and Clyde” (8 p.m.) and directed “Kramer vs. Kramer” (10 p.m.), “The Late Show” (midnight), “Still of the Night” (2 a.m.) and “Nadine” (4 a.m.).

It’s Houston at Golden State (ESPN, 9 p.m.) in game one of the NBA western conference finals.

It’s Chicago at Anaheim (NBC Sports, 9 p.m.) in game 2 of the Stanley Cup western conference finals.

Baseball includes Texas at Boston (MLB, 7 p.m.) and Cubs at San Diego (MLB, 10 p.m.).

Tonight is also the NBA draft Lottery (ESPN, 8:30 p.m.).
