Detainee was allowed time to think about what he wanted to say regarding his travel to the US and would be given the opportunity to go to sleep. (fact is that intel officer was going to get a picture of A for interrogator to show detainee at a later time. Next shift should see if detainee can identify this as the A he mentioned.) Detainee was taken to restroom and asked if he wanted water. Detainee refused water. Detainee was then directed to go to sleep.
