WikiLeaks and Counter-Terrorism: People of Britain, Uncle Sam is Watching You
From a practical point of view, the idea that the CIA could simply move in and recruit informers in British communities is far-fetched. It also would be extremely bad form for the intelligence relationship between Britain and America.

The likely scenario is one with echoes of the Cold War in which US Government money is being routed through numerous channels to address the perceived UK security threat.
