Re: I feel sick
"Seriously, this is the 300 kg gorilla that never seems to get mentioned here: you can't spy on terrorists and kiddie fiddlers without also spying on you and me."
But you can have processes in place to make sure the information they get is proportional and not too invasive, if it turns out that the suspect is innocent.
It's called a warrant.
The police can't just wander into your house, but if they suspect that they need to, they can apply for a warrant, and someone outside the police will decide if the need is justified.
Most people's objection to the snooper's charter is that in a lot of cases there is little to no oversight, and if there is, it's behind closed doors.
