Some random thoughts on this for which I'm going to use your post as a springboard

.
1. I think whoever is responsible for releasing the information, since it's clearly irrelevant legally, is guilty of ethical misconduct (not saying it's illegal, I guess this is how you play the game). Why? Because it serves no purpose whatsoever except to pollute the jury pool and make this guy hated. It's also going to open this woman up to unprecedented scrutiny, I hope she's told them that's OK because that's what's going to happen now.
2. I predict this
may backfire. Have they established the credibility of this woman's accusations? I think some in the media are going to look at this a little harder than usual and be more inclined to question the accusations because of the nature of them, since if it's true it means he was molesting his cousin at age 8. If the accusations don't come back as credible it
might backfire and make the prosecution look bad. Of course if they come bac as credible, it'll make GZ look like a seriously demented guy.
