Two points. It is obvious from the film of Trish Cameron and her mother that ‘jemmied’ is not a word that would willingly come to Trish’s mind, in fact she has trouble with the pronunciation, suggesting whoever she spoke to used the word. That person was Gerry.
Further we were told that by the time Gerry spoke to his sister he had already tried to raise the shutters from outside and found that he could. From that point he would have known that there was no need to jemmy anything, therefore why tell his sister that they had been ?
Good points, well made. I forgot about that; she was unsure of the parlance herself and even looked a little embarrassed and apologetic using the term. She was repeating verbatim, despite not being familiar with the word itself.
Besides, you
know when a shutter / door has been jemmied / levered / cracked open. It's a destructive act, and one that is carried out as a last resort - hence why supporters must insist that Gerry and Kate never
actually said it.
Our abductor however, according now to Gerry, needn't have bothered to bring his crow bar, the shutters move freely from the outside apparently. Which is it?
