Cunning, Fiendish al-Qaeda Muppet Menace Strikes Again?

Hmm, interesting.  BBC is reporting a previously blacked-out story of a 'major' (their words) anti-terror trial in London, ending with a partial guilty verdict.  However, one thing strikes me as slightly out of whack in what is apparently a tale of...

one of the most important recruiters for Islamist extremism in the UK
...
a key figure in extremist networks.

...to whit:

Hamid told the arresting officer he was "Osama bin London" and armed with a bomb.

Now, slap me with a haddock if I'm going out on a limb here, but isn't this a bit of a stupid thing for a Fiendish Islamist Masterbrain to do?  Or is he another thick fantasist muppet, like Dhiren Bharot or the Glasgow firebugs, dearly wishing to be a Great Warrior but not having a clue?  No doubt as he's led away he'll be kicking himself, saying 'you idiot, Mohammed, you should never have told that policeman you were Osama bin London, now our plans for world domination lie in ruins'.  Prat.

[Obviously, with only the result and prosecution case reported, this is another sad day for British justice, too.  I'd like to know why he was acquitted of some of the charges, given the recent record of the CPS in trying to pin unstickable stuff on people]
