You know, in order to compare signatures, you would need to get a sample from the time that he wrote in the yearbook. Why? Because signatures change as a person's job changes, or as they get older. I know that my signature as a high school student and a young man is much different than what it changed to when I made supervisor.
Why did my signature change? Because I had a hell of a lot more stuff to sign as a supervisor, and had to be able to sign it quicker than I used to.
Although, since I retired from the Navy, my signature has stayed pretty much the same.
And, because Moore is a lawyer and more than likely has a lot of documents that he's signed on file with the county, it would be no problem to ask for copies of those documents and compare signatures.
But like I said earlier in the thread, please get a legitimate handwriting analyst and not some journalist who is trying to make a name for himself by defending Moore.
