I'll have as much sympathy for the Carr's deaths by execution as I had for Smith and Hickock the two "In Cold Blood" killers. I read the book and saw the movie. The movie tried to take a sympathetic look at the killers, and it took an anti-death penalty stance. Myself I couldn't wait until they dropped those two b*stads through the trap door. I only wish the Carr's demises will be as painful.
I used to live in Garden City, and Dodge City. I lived within walking distance of where the Clutter family are buried, and used to hunt and shoot within sight of the Clutter family farm. Perry Smith and Dick Hickock were choirboys compared to these two. They didn't tortured their victims, rape them etc. still they deserved to die just like they did.
I would give odds, two to one, maybe even three to one that the little girl who recanted her accusation of rape was in fact telling the truth the first time. It fits their later actions so perfectly.
