On Aug 16, 2013, Canadian filmmaker John Greyson and Palestinian-Canadian doctor Tarek Loubani were detained without charges in Cairo's Tora Prison. During their 50-day detention, John created these flash cards as a diary of their experiences. Following an international grassroots campaign, they were released on October 7, and returned to Canada on October 13. This video is dedicated to the many who spoke out for their release, and for the many who are still behind bars.
