Like the saying goes, if you outlaw guns, only the outlaws will have guns.<p>Seriously. Ever heard of steganography?<p>Police being able to listen in to communications for selected individuals, based on court orders is of course something that is necessary for safety, nobody is arguing that. The difference is the scale of the ability to survey. You can argue that the scale doesn&#x27;t matter, but it does. The only difference between uber and your local taxi company with 10 cars is also scale. Being able to scale surveillance trivially is the thing that must be fought against, because it erodes the freedom of people. After all, the freedom of people to live their lives as they wish is what we&#x27;re protecting after all, isn&#x27;t it?
