You have said this one way or another a few times, but I just thought I would point out that "nobody cares about this but it will ruin their chances of election to oppose it", doesn't on the face of it make a whole lot of sense.
It's simple. Nobody, besides us nerds, cares about the details. Unfortunately it's extremely easy for those in the media to paint this as 'isis loving Labor allows terrorists to communicate secretly' and that gets every man and his dogs attention, because privacy and civil liberties is a thorny, complex issue, but terrorist bashing is easy low hanging fruit we can all agree on.... right?
