The men's personalities and profiles have been particularly confusing to grasp due to the number of conflicting accounts published in the media. Mainly unconfirmed security sources and anonymous acquaintances have fuelled the notion that these men were indeed Islamic terrorists influenced or perhaps even trained by Al Qaeda. But there are still friends and family members who do not accept that the men they knew were capable of committing such acts.

[hardly the behaviour of an Islamic suicide bomber]
Guardian: The suicide bus bomber Hasib Hussain made frantic telephone calls to his fellow bombers minutes after they blew themselves up on London underground trains on July 7, it emerged last night.
[why would Hussian be frantically ringing the other men if he was aware of and part of a suicide plan?]
Guardian: 'Detectives believe that Hussain had initially planned to board a Northern Line train but was unable to do so because of engineering work at King's Cross. Seemingly unsure of what to do and unfamiliar with the area, he wandered around aimlessly for more than an hour.
He is believed to have left King's Cross and walked towards Euston station, before boarding a bus which became caught up in the heavy traffic that followed the tube blasts. He then got off and boarded the No 30 bus heading south.'
[there are a number of other tube lines Hussain could have boarded - why would he wonder around for an hour and then get two buses before detonating a bomb? Why did it take police so long to establish Hussain's movements? Why are the police still not sure what happened even after thousands of cctv tapes have been analysed?]
Independent: 'The teenager who destroyed a double-decker bus - was also captured on surveillance cameras wandering around the streets of London, "bumping into people", before detonating his rucksack bomb.
The unnamed official told delegates that Tanweer argued with a cashier that he had been short changed, after stopping off at a petrol station on his way to the intended target in London.
The official told the seminar held in Preston, Lancashire two weeks ago: "This is not the behaviour of a terrorist - you'd think this is normal.
"Tanweer also played a game of cricket the night before he travelled down to London - now are these the actions of someone who is going to blow themselves up the next day?'
