Ha Ha - I thought that "getting coffee" would surprise you.
Seriously though, the CIA are now "Creators of Fiction" and, like any out of control military organisation, seem to have their own self-fulfilling agenda rather than working to keep the US (or anywhere else) safe.
As for the CCTV cameras in London, they are on the main streets and shopping areas and not on the streets where most people have homes.
To tell you the truth, I would prefer it if every single road and street in London was blanketed with CCTV cameras, as long as they are not planted in my home then I am not worried.
