I think that Cheese is onto the exact reason that Abby's classification has not changed. The analysis of the letter would have been very different depending on whether it was hand written or typed. Handwriting analysis can tell a lot with regard to line weight, stroke, etc as to whether it was written under duress and a typed letter has its own set of unique criteria for determining authenticity. It is my belief that FBI employs the very best in these fields and I feel confident that they have done that so it does not surprise me that between Nov 6 and the PC on Nov 22 that it took that long to analyze it. Of course at that time we had no idea there even was a letter from AH, but looking back I can see that Zenya's letter was a response to the letter that they received. It was short, simplistic and handwritten. I think that is significant.
"Abby's mother has asked to make a plea to Abby..."
not really IMO. ZH is not comfortable at ALL with public appearances.
"Dear Abby I believe you're out there, somewhere, watching and listening to me right now..."
I feel that this is an attempt to illicit a reaction, that if it WAS written by Abby to respond again, this time with a
hand written letter like I have.
