Dear Callan,
I never said she lied. I think it matters not which hand she wrote with. I do know that you said, verbatim, this:
"Patsy Ramsey was specifically asked in a police interview, whether or not she was able to write left-handed. She indicated that she was, to an extent that was better than most people. Why did she just not say no? Even the most stupid of people would know that this was leading somewhere, so if she had murdered her daughter and had written the note left-handed, all she had to say was - NO!
How on earth is anyone going to prove otherwise? Yes, an old member of her school class said that she could, but so what? all she had to say was that she must have been mistaken, or that she was lying."
It sounds like you are stating Patsy was ambidextrous and were using that as an argument to prove your idea. Have I misunderstood you?
I have no idea whether or not she was ambidextrous. Her housekeeper said she had seen her write with both hands. I do not know about the school mate you are referring to. It doesn't matter to me because expert QDEs could not eliminate her no matter which hand she used. That's what's important.
