Yasiin Bey, aka Mos Def, is subjected to the Standard Operating Procedure for force-feeding prisoners on hunger strike at Guantanamo Bay. In distressing scenes he is restrained and force-fed until he cannot take it any more.
An unknown number of prisoners in Guantanamo are on hunger strike is in protest against their ongoing detention, despite the vast majority of prisoners never having been charged or tried, and over half the remaining population having even been cleared for release by the US Government. However, their peaceful protest has met with an increasingly aggressive response from camp authorities, including force-feeding and violent procedures known as 'forcible cell extractions’ (FCEs).
On 2 December 2013 authorities stopped releasing figures of the number of prisoners on hunger strike and being force fed (you can see the time-line from the begining of 2013 to the present here). In July 2014 a navy nurse became the first to refuse to force feed the prisinors, declaring it to be a criminal act.
