Definitely they're in that category.
Having met some of the Birmingham six and Guildford four, who were gentlemen and always welcomed me for chats in their cells in Scrubs and Long Lartin in the eighties.
Ray,
I have a particular interest in the Birmingham Six case, so may have some questions for you! (I have not forgotten your own case, either. Will add a post to your thread soon).
At this point, I am undecided on Luke Mitchell, but I am definitely leaning in a particular direction. What I am reading and hearing does not inspire confidence in the original investigation.
