Of course I'd rather not have big brother watching my every move but I continue, undaunted, to support the government's efforts. Although they do need, as xpressed by Zen, to clarify exactly what's needed.
One thing the UK has proven itself quite good at (understatement in extreme) over the past century is intelligence gathering - anybody who thinks otherwise should pay a visit to Bletchley Park. Moreover this country has had more experience than most, in later decades of last century, of dealing with terrorist threats. The government and security services really do deserve some recognition and cooperation, IMO.
It seems incredibly naive to me that the country's computer geeks should now rise up and assume that they know better, and tell the security services that they are 'doing it all wrong'.
No need for flaming though, I'm aware I am the minority.
