Where they suicide bombers?

[Gerschwin]

A guy in work was telling me about some info he read about the London bombers. The latest is that they probably weren't suicide bombers but more then likely tricked into becoming so (although they were obviously extreme fundamentalists)

All the bombers had various forms of ID on them - not the behaviour of a true suicide bomber
They bought return tickets on the train
The car had a parking ticket on it - paid for 4 hours

There were a few other interesting things about them that slip my mind.
I can't actually find any info on the web to substantiate what he read so can't verify this info is actually true.

Anyone read anything similar that can confirm this info has been released and is true?

In fact just found this site - http://volokh.com/posts/1121144161.shtml

I suppose they could have been innocent dupes who were asked to deliver some important packages.

They may have been supposed to plant the bomb and get out - the less people with info on the ring leaders the better so they never did get out....?
