Sunfish - Freedom, for freedom's sake, is a non runner, real freedom can only be achieved by good security. Right now the security services are up against some very clever and very evil people, the security services have to think on the run and may well require to be innovative and non conforming, it doesn't matter, what ever it takes to keep the peace and save lives as well as preserve your precious freedom has to be acceptable.
The idea that you can have peace and freedom with a security service that is hide bound by a set of published rules and no latitude to operate outside those rules is just a Utopian pipe dream.
I really don't see how "are(sic) friend" Notsofantastic, by stating the bleedin' obvious, can, in any way, be detrimental to the cause of freedom.
