Cops decry Waze traffic app as a "police stalker"

Police officials have lobbied for the right to conduct a variety of unfettered electronic surveillance tactics on the public, everything from being able to affix GPS trackers on vehicles to acquiring mobile phone cell-site location records and deploying "stingrays" in public places—all without warrants.

Some law enforcement officials, however, are frightened when it's the public doing the monitoring—especially when there's an app for that. Google-owned Waze, although offering a host of traffic data, doubles as a Digital Age version of the police band radio.

Authorities said the app amounts to a "police stalker" in the aftermath of last month's point-blank range murder of two New York Police Department officers. That's according to the message some officials gave over the weekend during the National Sheriffs Association meeting in Washington.
