Anything this man says about GCHQ is worthless, he is not in GCHQ.
Could be he is talking about the MI techs who are employed directly by MI: I know one, since he was in the Army, and whilst he never discussed operational activities we sure discussed technology, just as much as members of other professions do.
This stuffed shirt could lie his face off about GCHQ and then say, oops, my mistake, and do a CLAPPER.
If you want a 'look see' into present day technologies, keep an eye on patent filings! A real treasure trove of information. University people love 'publishing', they publish masses of things on arcane things but there is gold to be had there, too.
Secondly, this mouthpiece was reading from a really well edited script. Delivering a message. And misleading casual listeners.
The point is the public (unwittingly) trusted the politicians and government agencies to look out for our interests, silly us, and they have abused this trust. They shot their load, and now they want another go round?
And the politicians were complicit in these dealings or asleep in their seats.
THIS IS HOW THESE ABUSES ARE PASSED INTO LAW. Hey, but who cares, I don't see any protests so the MPs will just support the rules without even considering the implications.
These agencies should be headed by people outside the business. Parker's viewpoint is myopic, he can't see the bigger picture. If heads from other walks of life were in charge, they would likely have different perspectives than people like Parker.
All legislation should have sunset clauses so when coming up for renewal, new technologies can be considered.
WAKE UP BRITAIN, THE POLICE STATE IS ALMOST COMPLETE.
