Youssef and Ramzi bin al Shibh

Four face recognition programs match my dinner companion Youssef’s photo to all these photos of Ramzi-bin-al-Shibh Ramzi is a Yemeni national held in Guantanamo Bay prison since 2002 and is accused of being an al Qaeda operative, a "key facilitator for the September 11th attacks". He is sometimes referred to as the ‘20th hijacker’ because he applied for a US visa before 9/11 but was refused. 

I suspect Youssef may be the brother of Ramzi bin al Shibh
