Hi tkc,
Maybe. But knowing this, he owed Z the protection of his authority and the presumption of innocence.
Instead he's manouevred the cloud of suspicion back over his head. He did it because he didn't want to tell the multitudes the truth. He did it for political reasons when the AG is the person to represent the requirements and principles of the law. Z is not guilty under the law and should be provided the presumption of innocence by the AG if he has no case to answer.
No one tells the goddam truth. It's all mush and cotton wool and calculation to palliate people who ought not to be palliated. And to pass the cost to someone who should not have to accept it. I don't respect that so much.
