I was really pleased to come across this story. Brandon Neely, an American solider who worked at Guantanamo used facebook to make contact with two former British prisoners. He wanted to apologies and accept his responsibility for the injustices Shafiq Rasul, Ruhal Ahmed and other Guantanamo Bay prisoners have suffered.
This BBC website includes two short films - Tales from Guantanamo- telling the three men's stories and recording their meeting. Well worth a visit. Had my eyes damp!
