According to the Huffington Post link DennisR provided in his Post # 244, at Allred’s request, "an expert had analyzed the GOP Alabama Senate candidate’s handwriting and signatures in public documents and compared them to the message and signature in Young’s yearbook". In other words, Allred either hired that "handwriting expert" for some huge amount of money to say what he said about the yearbook, or she looked far and wide until she found her own "handwriting expert" willing to say what he said, possibly because he is a political kindred spirit to Allred.
Notice, she still has not released the yearbook so that independent experts or Moore's lawyers can examine it for themselves, and render their opinions on the fishy yearbook writing.
As I said in a previous post in this thread, handwriting analysis is not an exact science, and so-called "experts" often disagree on their findings (sometimes based on who is paying them). We know that Allred is a frequent liar, and we know that her client (Beverly Young Nelson) is also a known and admitted liar, so it is absurd to think that Allred went searching around, and found an honest, trustworthy, incorruptible, independent "handwriting expert" to verify her lying client's far-fetched story.
A real expert would also test the ink.
