Read Baase & Henry Chapter 5, on Computer Crime
The Supreme Court ruled 5-4 that the police do need a warrant for more than seven days worth of a phone's cell-tower-connection data. This information spells out the approximate location of the phone, often to within less than a quarter mile. In principle, a record is made whenever a phone moves within range of a new cell tower.
This decision is a major departure from the third-party doctrine, under
which information about someone that is in the possession of someone else
can be turned over to the police without a warrant. Traditionally this
applies to "business records", such as banking information and phone-call
metadata.
