He was one of the moat colorful witnesses who appeared before the Bayh Subcommittee. Capote testified against Miranda in 1966 on the ground that the killers he chronicled throughout In Cold Blood would not have been convicted if the Miranda warnings were in place. (That’s far from clear, by the way). In his prepared statement, Capote said this:
“I have never met an innocent man who has confessed to a crime he didn’t commit.”
I’m sure this was true, but it was also irrelevant. Lack of personal knowledge says nothing about the existence of that thing. (I’ve never seen a dingo, but that not mean there aren’t any.)
Capote also said: “I have never met a murderer who would willingly confess to his crime with the protection guaranteed by the Miranda decision.” Again, true but beside the point. But he did get the Subcommittee headlines. Senator Bayh was pictured with Capote in the papers the next day.
