...do watch this gruelling BBC documentary. Made in the eighties, it follows a young man through the
last fourteen days of his life, leading up to his execution in the gas chamber of Mississippi's Death Row (he was later proved to be innocent). This film shows the sheer brutality of his execution, and the dreadful punishment it inflicted on him, his family and the officers around him who believed in his innocence. Please watch it if you can spare the time. I saw it when it came out, and have just watched it again, and I have rarely been so moved or so enraged by a documentary.
