We can meet in my basement and discuss further. I'll have my mom pickup some orange juice, crackers, and lots of tin foil so we can fashion tin foil hats to block the gamma rays sent out by government tracking satellites that can read our thoughts.

In all seriousness though, i think most conspiracy theorists are whack jobs that just take shots in the dark, and when shit does go down it looks like they were right all along. That being said, london does have a lot of different nationalities, and a lot of the nations those people are from hate the western world. I wouldn't be surprised if something happened but I doubt it being the plan of a secret organization or something, if that's what you're eluding to.
