Plan of action...
Before anything can be done politically to fight for individual rights against state surveillance, there needs to be a careful analysis of which laws have been passed to grant these powers in each country. Then a reasoned debate over exactly how those laws need to be changed - where the line needs to be drawn to protect citizen's rights. I'd say if someone created a forum for this purpose (split on a per-country basis) and published it widely that would help start the ball rolling...
Cases of abuse of state power should serve to motivate the public to support this movement politically. I suggest people search for "Covert Harassment" to find out more.
