not reportedly, he claimed like that. do you think when kashmir singh was captured, he might have said that he came by intention and is a spy. he revealed this only after getting released....
spies should be treated by the las of land.. only thing he should be given full and fair trial not like what happend in the case of afzal whose case has never been represented from his side, rowdy lawyers did not allow any one to represent him.. dont let this hapen to sarabjit. try him and if he found guilty punish him the law of land.
