Note the increased awareness brought by widely available cameras with immediate upload capability. The commenter above implied this is dystopian, but the opposite seems to have occurred -- as the public gains the capability to surveil the state, it constrains the state.
One case that personally always bothers me was regarding the murder of Philando Castile.

Technical solutions to privacy are not required to be alone. They're required to be ubiquitous. If your country is an authoritarian hellhole, you encrypt everything to help you not get murdered by the secret police. If your country has strong privacy protections, you encrypt everything to help ensure that it never becomes an authoritarian hellhole, and protect you against bureaucratic failures as defense in depth.
To invade your privacy, an attacker should have to break the law and break the encryption.
Even if you're innocent, they'll make something up. I lived for a year in one of those authoritarian hellholes and in that time knew two people who were arrested and hauled from station to station til someone paid a bribe- these weren't the dissidents either, just some guys. The dissident was stabbed to death on his doorstep.
Encryption is good to save us from marketing, from megacorps making our lives hell. Laws and norms constrain the rest.
What’s needed is an agreement between all of us, in the form of privacy laws, that make certain uses of this data illegal.
In the future if you’re caught committing a crime by data captured in a manner illegal under these laws, it would have to be thrown out and can’t be used against you. Corps would also be banned from collecting, storing, and using personal data in an unlawful manner.
Feels like a pipe dream since there’s so much money in the industrial advertising complex, but I’m pretty sure that’s what it will take achieve reasonable levels of privacy.
