".....Q Why did Mr Haneef buy a single way ticket even if you have not resigned? A I was not supposed to go back. ..."
A Person is innocent unless proved guilty. Also the question which you have raised does not prove anything. Many a times a person does not know exact day of his return while visiting family members.
Lastly - if there are two possibilities why are we trying to look at the negative one - when the reputation and entire lives of families involved is at stake ?? Lets not jump to conclusions - After 9/11 attacks many so called suspected terrorists supposed to be part of the suicide mission were found to be alive. Hence let us not be blinded by religious bias.
