Nethercott is a convicted felon and was arrested earlier for being in possession of a firearm, I show nothing on Riddle. Without going into detail, there is more to this story than what is in this article.
I agree with the tone of your comments. I do believe there were grounds to go after this guy. From the comments on another thread from people I trust, I do believe this guy was a loose cannon. As I said in a previous post here, the problem is, the FBI just simply doesn't have any credibility any longer. That's a real shame, but it's the truth. And the FBI itself, is the only party to blame for that.
