The Supreme Court recognizes that we are entitled to some digital privacy and safety from unwarranted searches.
To demonstrate how cellphones differ from other items that you might be carrying in your pocket, the Court chronicled, in some detail, the many functions of cellphones – as “cameras, video players, rolodexes, calendars, tape recorders, libraries, diaries, albums, televisions, maps, or newspapers” – and emphasized their “immense storage capacity.” Having all of this information stored in one place, the Court explained, collectively provides much more information about our lives than, say, a calendar or camera would, standing alone. In fact, the Court posited, because of the different kinds of data that can be stored on a cellphone, searching a cellphone could provide police with even more information about your life than they could get from searching your home.
If this kind of aggregation is what it takes to stop the piecemeal destruction of the 4th amendment, then great. Go google. Maybe this can reverse the flow.
