To me, the main question is: "How is it possible that he is still alive after 17-years in an American prison?"
Therefore, IMHO, every other prison inmate who crossed paths with him should get an additional 10-years added to their time!
I believe I read that he was in isolation 24/7 with an hour a day escorted exercise walk in a empty court yard. The BOP didn't want Lind to be a martyr and they didn't want him to be able to smuggle messages in and out via muzzie brothers behind bars.
