Lady Liberty rejoiced recently when a rare unanimous U.S. Supreme Court held that police may not rummage through an arrestee’s cell phone without a warrant. For years now, police officers have riffled through arrestees’ mobile devices with impunity. That is, until June 25, 2014 when the decisions in David Leon Riley v California and United States v Brima Wurie were issued by the court. But before we get too revved up about it, be forewarned. There are significant concerns we should have about any cell phone searches, even when authorized by a warrant. I’ll get to that.

First the good news, then the bad.
