If you're saying that he had legitimate defenses under the law and was denied those defenses, then fair enough. I haven't reviewed the case or the applicable law closely enough to say whether I agree or disagree. I just wanted to be clear that you weren't arguing that he shouldn't be prosecuted just because he's a good guy.
We do have an adversarial system. The DoJ will seek to bar any defense that might produce a jury instruction that therefore must be addressed with evidence to the contrary by the DoJ.
There are quite a few affirmative defenses one can provide evidence for. And, as I see it, that do not seek to negate an element of the alleged crime, like 'Presumption of Innocence'... But, the devil Republicans made me do it is not one of those...
BUT anyhow, it is not the DoJ who'd rule on the admissibility of an affirmative defense... it is the unbiased, non adversarial Judge.
IF DoJ does not bring a case against a person when a reasonable prosecutor would then we have the Unbiased DoJ 'in house' Oversight folks and the Congressional Oversight committees who look into that. Or they may not depending on who their buddies might be or how corrupt they too may be.... ()
IF DoJ brings a case against a person because they violated a law and do so as punishment cuz, let's say, they are of another political party and choose not to bring cases against folks doing the same thing but belong to their political party one might argue the same thing.
Remembering a crime has been committed in both cases... is kind of important.
While I agree that our liberty is secured in part by virtue of our justice system I don't find an attack on our liberty occurs when our justice system enables the conviction of a truly innocent person. It is the best we have but it is dependent on at least one side playing fairly... the prosecution has that burden.
EDIT.... Somehow my last statement did not appear....
I don't think it is a defense to suggest because something is morally wrong that some tangential criminal act is ok... (sounds like a move toward jury nullification to me) Some think there exists a right to life so it should be ok to terminate abortion doctors.... That is an extreme but seems on point... like Broccoli.
