Experts: More evidence needed to know if Moore's yearbook inscription is real

“What a true forensic examiner will do is look at as many samples as possible from as broad a time period as possible,” Steven Drexler, a retired handwriting expert and document examiner from the Alabama Department of Forensic Sciences, told NBC News. “Everybody’s writing changes over time.”…

“People have narrow or wide ranges of signature variations over time,” he said. “And some people have different signatures for different tasks. I know some attorneys who have what I call credit card signatures which are illegible and more formal legible signatures for court documents.”

Drexler declined to weigh-in specifically on Moore, saying that anybody who would issue a judgement based on the available evidence is a fraud. “The woods are full of snakes,” he said.
