Judge Actually Recognizes The 4th Amendment: Says Police Can't Get Location Info From Telcos To Arrest You

From Techdirt:

With all the reports of law enforcement collecting tons of location info from telcos without a warrant, as well as a bunch of court rulings that seem to chip away at what's left of the 4th Amendment, it's somewhat surprising to see a magistrate judge say that police cannot use a warrant to find out your location from a mobile operator, for the purpose of arresting you.
