A few years ago it seemed like the answer was "because TERRORISTS", now they're also talking about organised crime and child abusers.
This government have already branded the leader of the opposition a 'treat to national security'. Which leads me to concluded that they are either lying, incompetent, or reading all his internet history too.
Furthermore, I've heard no compelling arguments as to why the idea of an independent judiciary (who should be the only people who can issue these warrants) is broken, or how it should not apply when it comes to the online world.
But the drip drip drip of obfuscated and fear motivated erosions to the balance of powers continues, and it's making me deeply worried about what kind of country my grandchildren will live in.
