and equally there are several experts who have concluded she did not write it ! eg Richard Dusak of US Secret Service who was instructed by the Boulder PD
Excuse me, but there was not a SINGLE expert who said she did not write it! None of them used those words, not even the three the Ramseys hired to do it.
The man you mention, Richard Dusak, has several problems. For one thing, we don't know how much material he had to work with or how much time he spent on it. If he were contacted by the DA and not the police, I wouldn't be surprised if they "worked" the results to favor them. For another, I'm reminded of two things Gideon Epstein said: one, he doesn't know how much actual examination work Dusak did, so his experience might be questionable; two, he wasn't contacted until after the two Ramsey-hired experts had made their decisions. As Epstein pointed out, government handwriting examination is a very small field, and nobody in that field wants to go against anyone else because it would call the profession into question. AND, I would not be surprised to find out that the two Ramsey-hired guys put the word out, "Hey, don't go against us, because we'll make you look like monkeys in court."
Tortoise is right: Dusak's report isn't worth the paper it's printed on.
