Carpenter v. United States (Argument November 29, 2017)

CarpentervUS

This case has been decided. See how it turned out!

This case gives us a chance to review the progression of the 4th Amendment – our privacy from government intrusion.

When the 4th Amendment was enacted (in the Bill of Rights, 1791), people were concerned with physical searches. Today is an era of electronic communications and big data. Government access to private information is a completely different ballgame.

In this case, Carpenter and Sanders were convicted of a series of robberies based on their cell phone location data. The FBI got the information from Carpenter and Sanders’ cell phone service providers without a warrant.

The FBI did not have to show “probable cause” because the 4th Amendment did not apply. Instead, the Stored Communications Act did.
