But there's no evidence anyone actually used any such technique.In post #161 at the top of the last page @Beekarina posts an article which explains how this exact same locking system was professionally tested and was easily manipulated/ locked from the outside with a piece of string passing through in seconds then quickly concealed in a pocket.
I've noticed that someone very dedicated a particular theory will often go to any lengths to promote it and try to overcome all objections. And it's all fun and games
I'm just glad it's not the way law enforcement does investigations: coming up with theoretical ways to invalidate the evidence, so they can continue with their pet theory and, for example, prosecute someone who is innocent.
