Few people realise that they are being watched from above.
[sbpost.ie] For example, there is a regular presence in the sky above some
English cities of RAF SigInt (signal intelligence tracking) aircraft
that intercept all signal communications, especially those from mobile
phones.
The aircraft concentrate on cities with large Muslim
populations, such as Bradford and Birmingham and areas such as east
London.
This extraordinary level of surveillance began after RAF
Nimrod aircraft, monitoring Taliban radio communications in Afghanistan
in 2005, began to pick up Taliban militants with Bradford or Birmingham
accents. Since the July 2005 bombings in London, the search has been on
for returned British militants.
This has led to aerial
surveillance of cities where they might be based. (more on sbpost.ie)
