Debunking london bombing theories, first problem, survivors who should have been killed, but miraculously weren't saw the bombs go off.
2nd problem, CCTV footage of the events exists, which was recorded and by civilian subcontractors who's companies work for the london underground as part of a PFI (private finance initiative) programme.
3rd Problem, forensic evidence, remains of the bombers at the scene, bank cards and other identifying property on their bodies.
4th, CCTV at Luton though blurry due to poor framerate, those men can be identified at the train station at the right time to get to london, and the 'train cancelled theory, is rubbish anyway, as the train they caught was before the cancelled service anyway.
5th, Bombs found in car at Luton.
6th Bomb residues which matched explosive substances used, were found at Alexandra Grove Hyde Park Leeds.
7th, its a bit big to cover up.
