The Bill of Rights was published over 200 years ago. It can't possibly anticipate the modern privacy landscape. We need to (and do) extrapolate from the intent of the Bill of Rights to cover modern technology. Protecting phone and internet traffic is an example of this, but no longer sufficient. The US is becoming a panopticon. The Fourth Amendment protection against wiretapping is insufficient when the government also collects so much metadata. If we cede every form of privacy not explicitly protected by the Bill of Rights, we will soon find that on their own they provide barely any privacy at all.

Hahaha who am I kidding, that ship has sailed. It's a lost cause.
