London: Explosive Devices Found
Police denied that they had recovered any unexploded devices. But a source told The Guardian that three controlled explosions had been carried out on "suspect devices".UPDATE: Keep an open mind with what the media is reporting; via H, a local poster from London...
Furthermore Vincent Cannistraro, the former head of the CIA's counter-terrorism centre, told The Guardian that "two unexploded bombs" were recovered as well as "mechanical timing devices".
The Media over here is a little more subtle then say fox news, however we have a system over here called the "D-Notice." A D-Notice can be put in effect by the government if they believe it is in our interest not to know. A-D Notice makes it a impossible for the Media to report on anything that the government deems to sensitive for our consumption. For more on D-Notices go to Wikipedia.
There is no doubt (considering what this tactic has been previously used for) that the concept of a suicide bomber on the underground would be covered by such a procedure.
As for what we are being told... same as you. A slow methodical walk towards the subconscious understanding that these devices were detectable and hence preventable.
It has to be timed devices, they like it when we live in fear (both the US and UK government seem to follow the doctrine of Machiavelli), but if the actions of our government has brought suicide bombers to our country, then that fear would be turned on those that brought such a drastic change in British terrorism.
But the whole point of such fear is to make sure we trust the government when they say we have to do this or that for our liberty.
Regardless of it is, or isn't suicide bombers... the conclusion will be that it wasn't, or if they have to conclude something, then it will be stated the suicide bomber was singular and only applies to the bus.
