Since knowledge of jury nullification is far from widespread, and any mention of it during a trial would likely lead to an immediate mistrial, I think he is correct not to begrudge the jury their verdict.
Ignorance only benefits the powerful. The judicial system can and will keep jurors ignorant about this, while a defendants cannot claim "ignorance of the law" as a defense in their case.
It's strange. I remember jury nullification from my Constitution class, which is required to get a high school diploma in the US. Actually, it may have been required to graduate from middle school.
