I don't go much for conspiracy theories, but....
At work today, someone was saying that the Olympic security fiasco is a set up.
That intelligence are increasingly concerned about potential terrorist attacks, which is why they have drafted in military. G4S have received a kickback to go along with the story because the government really need the games to be a financial success, and don't want to put people off travelling to London. That the media are making a big deal of it so that potential terrorists are aware of the military presence.
Usually conspiracy theories are flawed - help me find the flaw in this one.
It's got me wondering.
Btw, my colleague works in security.
