'Cold Case JFK' review: Minds won't change

That's why "Cold Case" -- as gruesome or brutal as anything you'd see on "CSI" -- is almost a morbid kind of comfort food. There's no wild-eyed theorizing here, or crazed claims of a squad of gunmen crouching on the grassy knoll. All it says, in effect is, "Here's what we did, and here's what we found out. You draw your own conclusions." Lucien Haag says of a forensic investigation: "If you can rule out the impossible, that which remains, however seemingly improbable, is the truth."

Neither he nor "Nova" make a claim on the "truth" here, but they do make a plausible case for what most likely happened: A single Carcano bullet struck both the president and governor while the third shot was fired from above and behind JFK, and not from the grassy knoll. If you're a hardened JFK conspiracist -- and you are certainly not alone -- there's little chance this "Nova" will change your mind, but it's so calm, reasoned and expertly argued that you might just be pleasantly surprised.
