A recent Supreme Court decision has implications for cellphone users' privacy. The court ruled that constitutional privacy protections apply to cellphone location information. This decision came in the case of a bank robber who was identified using a geofence warrant.

The ruling was made with a 6-3 vote, with Justice Elena Kagan writing the opinion. It establishes that individuals do not give up their privacy rights when their location is tracked through their cellphone. Further details on the ruling and its potential impact are available from the source, including the full opinion written by Justice Kagan.
