Secret organisations should be so secret that everyone knows about them. Templars for instance. Everyone knows about them, everyone thinks they exist, and therefore no one believes that a small group of individuals could actually be the Templars because then what? Similarly, the Illuminati. There are University groups you can join to become part of the Illuminati, and therefore the society can operate undercover (if it exists) without arosing any suspision. Preferably you would also release TV/Radio programs filled with conspiracy theories and nut jobs telling people that they(The society) exists, leaking genuine with the fanciful. However, in order to keep stuff secret, I assume they have installed several minor flaws in hover/vechicles, causing them to accidently-on purpose run into buildings containing evidence and then blow up. In addition they probably use subtle means as well, such as doctoring photos, character assassinations of witnesses...The whole Scientology bit. Preferably all done under a shill...Alternatively by the sort of wierdos that people just roll their eyes...like the 'Leave Britney alone' person. In simple terms, 'Look at the feet because you aren't watching the hands'. I would imagine the British would take a more laid back view of events because it is assumed everyone will play cricket. If they don't...well...thats not cricket...not cricket at all... I can't remember enough to be tremendously helpful, but I would imagine that the British would wait for something to go wrong before trying to solve it...Rather than trying to solve it before it goes wrong, and thus creating several other problems...and so on and so forth.
