L&O: He goes free for killing a cop but is charged with killing the cop killer

An armed robbery leaves an off-duty cop dead and the two gunmen flee by hijacking a town car. When Briscoe and Curtis find one of them, the robber offers Ross a deal: in exchange for a light sentence he'll tell them where to find the kidnapped driver. Over the cops' objections, McCoy agrees to the bargain, but they learn too late the driver was already dead when the suspect offered it. When the other robber turns up dead, Jack shocks Lenny and Rey when he decides to honor the crooked deal. He lets the first guy go for killing a cop so he can charge him with killing the other cop killer. But the entire thing could fall apart if Briscoe and Curtis don't lie on the stand and say they didn't tell McCoy the cause of the accomplice's death was murder. We're talking about the award-winning episode of Law & Order season seven episode nineteen "Double Down." Our returning guest is Brady Carlson from the "Cool Weird Awesome" podcast. The landmark case of Brady v Maryland serves as a plot point to this episode.
