Delaware courts: Police use of tracking devices at issue

Sean O’Sullivan reports:

A criminal case making its way to the Delaware Supreme Court could help define personal privacy and set limits on how far police can go when using electronic surveillance in Delaware and perhaps across the United States.

The American Civil Liberties Union this week filed a brief in Delaware v. Michael D. Holden, urging the state justices to uphold a lower court ruling that essentially bars police from using Global Positioning Systems (GPS) to track people without a court-approved warrant.
