London 2012 Olympic Police State http://www.gamesmonitor.org.uk/node/938

Security precautions for London 2012 include the construction of a 17.5 km, 5,000volt electric fence, topped with 900 daylight and night vision surveillance cameras spaced at 50 metre intervals. On first sight of the fence you could be forgiven for thinking you had slipped through a wormhole in the space-time continuum to find yourself on the perimeter of a Soviet era Gulag.
