Gerry was also advised to remain silent but he chose to do the right thing and answer every question to the best of his ability as far as we know. Kate on the other hand chose to remain silent which since it was her child who had gone missing was a rather puzzling thing to do. Suspects generally choose to remain silent when they have something to hide or their story just doesn't quite add up. So what was it?
How on earth did she think she was assisiting the investigation into her daughter's disappearance by taking the coward's way out? She should have answered every question and then asked some of her own.
AFAIK The option to remain silent is part of every civilised society's judicial system. The idea that it was introduced so that cowards could do the wrong thing is preposterous imo.
IMO Having read the questions - a blind man on a galloping horse can see that the motive behind them was not to find Madeleine - it was to find a reason to pin the crime on Kate.
IMO We know why she didn't answer the questions.
IMO It was because her Lawyer advised her not to - and not because she couldn't answer them. Obviously as a Portuguese lawyer he knew far more about what could happen to her if she did answer the questions than anyone else did - so why would she ignore his advice? That would be a really stupid thing to do imo.
When we know the sort of stuff that was considered to be vital evidence by the PJ - like the DREAM for instance, or wearing a black top etc etc - it was quite proper IMO for her lawyer to protect her from falling victim to that kind of mindset imo.
IMO Kate knew she wasn't guilty and so to expect her to do anything at all to help the PJ to pin the crime on herself is totally crackers IMO. But that is exactly what is being suggested IMO.
