Teoria da conspiraçao
A consultancy agency with government and police connections was running an exercise for an unnamed company that revolved around the London Underground being bombed at the exact same times and locations as happened in real life on the morning of July 7th.
The exercise fulfils several different goals. It acts as a cover for the small compartamentalized government terrorists to carry out their operation without the larger security services becoming aware of what they're doing, and, more importantly, if they get caught during the attack or after with any incriminating evidence they can just claim that they were just taking part in the exercise.
This is precisely what happened on the morning of 9/11/2001. The CIA was conducting drills of flying hijacked planes into the WTC and Pentagon at 8:30 in the morning.
