Let us suppose this is true. Is it possible that this actually dissuades judges from finding that police officers have lied? I’d worry that a judge who thinks that an officer’s testimony is not that believable, but who is not certain, might err on the side of crediting the officer — or at least declining to say anything about it either way — because of the severe consequences to the officer. In other words, I wonder if the severe consequences to being caught lying cause judges to underenforce the requirement of honesty. That could even lead to more lying in the long run.
This is all speculative, of course. I’d love to know whether this is right or wrong.
