Some of the evidence I heard was not sound, imho, guilty or not, it isn't trustworthy beyond reasonable doubt. Many experts, who weren't able to testify at her trial, say statistical and other evidence was flawed. She wasn't well served by her legal representation at all. However, I've not heard all the evidence and it's impossible to tell much from her behaviour as all you see are photos and brief recordings on TV. People can do all sorts of weird behaviours under duress. I met someone who was responsible for evacuating elderly people due to a serious fire, she carried out the task perfectly but was so anxious she laughed and giggled the whole time. I think Lucy's likely to have her case reheard or whatever they do.
