Now why might that have been the case? Almost inexplicable!

Sky News report an incredible piece of news from the 7/7 inquest:

'London bus bomber Hasib Hussain was sweating profusely and looked "nervous and exhausted" shortly before he blew himself up.

Witness Anita Dybek-Echtermeyer told the inquest into the 7/7 attacks she was struck by the 18-year-old's "bad manners".'

Now why might a terrorist about to kill himself and murder others look "nervous and exhausted" and are Islamic jihadis known for their good manners?
