Police aren’t supposed to enter our homes or listen to our conversations. We are free to go where we please, when we want, unencumbered.
We can, of course, consent to waive our right to privacy and often do. We share our address so that goods can be delivered, our financial information to be afforded credit, our medical information so that we can be cured and details of our life to friends to establish intimacy.
In other words, we draw lines. We share some things with some people and other things with others. We compartmentalize data according to its purpose. However, technology is breaking down those containers and the repercussions will be wide ranging and pervasive. As a society, we have hardly begun to grasp the issues, much less deal with them.
