Justification ... not wanted here
Where is the justification, from places like Iran (ho ho ho), that such powers IMPROVE the situation?
Asking for a human rights/democracy bashing piece of legislation without saying WHY or presenting a compelling business case doesn't make GCHQ or Theresa look very good. I suspect she may not understand the implications of putting backdoors into open source PKI encryption, or have had the consequences explained to her competently by an authority without a vested interest. Legislation supporting such (impossible I might add) activities needs to be justified by those asking for it, with more than a "trust us" punchline. "Think of the children" is tired and old. Society as a whole thankfully doesn't appear to trust those using such futile propaganda - so that argument fails.
Perhaps there is no justification after all ... ergo .... stop this "anti-British" erosion of basic freedom. Nothing to see here ... move along please. PLEASE!
