Some police departments are encrypting their radio communications but at what cost to public transparency?

WASHINGTON (AP) – Police departments around the country are moving to shield their radio communications from the public as cheap, user-friendly technology has made it easy for anyone to use handheld devices to keep tabs on officers responding to crimes.

The practice of encryption has become increasingly common from Florida to New York and west to California, with law enforcement officials saying they want to keep criminals from using officers' internal chatter to evade them. But journalists and neighborhood watchdogs say open communications ensure that the public receives information as quickly as possible that can be vital to their safety.

The transition to encryption has put police departments at odds with the news media, who say their newsgathering is impeded when they can't use scanners to monitor developing crimes and disasters. Journalists and scanner hobbyists argue that police departments already have the capability to communicate securely and should be able to adjust to the times without reverting to full encryption. And they say alert scanner listeners have even helped police solve crimes.

Rick Hansen says he's been listening to police communications since he was 13 or 14 and considers efforts to shut them off a way to make government less transparent. The Silver Spring, Md., man says they should use technology to keep sensitive information of the airwaves on a selective basis.
