Report says warrants needed for police GPS tracking

A bipartisan group of legal experts and former law enforcement officials says limits are necessary on how police can use GPS technology to track suspects.

The Constitution Project, a D.C. think tank, on Wednesday issued a report on location-based tracking, writing that a warrant should be required for any GPS tracking that lasts longer than 24 hours. Law enforcement should also be required to obtain a warrant before placing a GPS device on a suspect’s property, such as a vehicle, the report says.
