Police Stealing your Cell Phone Data

This is not cool at all.

"This is the Cellebrite Cell Phone Extraction Device (UFED) and it can be used by police to extract your cell phone data during a routine traffic stop. The UFED comes in a rugged, road-ready case with all the connectors needed to grab info from almost every type of cell phone and portable GPS unit."
Legally, during traffic stops, officers need a warrant to search your cell phone; however, if you give them your phone voluntarily, they can use these tools to search it. Next time an officer asks you to give up your phone, ask to see a warrant first.
