Reading about this case it feels more like a case of her legal team not doing a particularly good job (e.g. no expert witnesses called despite being available) than her actually being innocent.
Probably worthy of discussion because of its public interest and some interesting reasoned analysis in publications such as Private Eye etc.
However as ever as pointed out elsewhere, it does seem to have become another vehicle for various nutjob conspiracy theorists to hop onto unfortunately, which must exacerbate the pain for the victims families.
