Thia is most definitely not a joke and its been on the cards a while now, under the umbrella of the intercept modernisation program, the problem as usual is in having appropriate and transparent legal safeguards, without such safeguards in the form of court issued warrants and independent oversight appointees whom folks have confidence in the scope for abuse simply becomes a ticking time bomb with folks waiting on
when the abuse will occur than debate
if it will occur.
This is yet another sign of a government failing, good policies make good citizens, oppressive policies radicalise even the most easy going to take action.
[Update]
It seems the conservative party (the tories) have changed the name of the program when they revived it upon taking control of the govt, despite the whole program being put on the back burner due to public unease
