Pasadena Police Encrypt, Deny Access To Police Radio
An anonymous reader writes "There is media (but not public?) outcry over the Pasadena, CA police switch from analog radio that can be picked up by scanners to encrypted digital radio that cannot. 'On Friday, Pasadena police Lt. Phlunte Riddle said the department was unsure whether it could accommodate the media with digital scanners. Riddle said the greatest concern remains officer safety. "People who do bank robberies use scanners, and Radio Shack sells these things cheap," Riddle said. "We just had a robbery today on Hill Avenue and Washington Boulevard," Riddle said. "The last thing I want to do is to have the helicopter or the officers set up on the street and the criminals have a scanner and know where our officers are." Just prior to the switch over, city staffers said they would look into granting access to police radio chatter, most likely by loaning media outlets a scanner capable of picking up the secure signal.'"
So, the police have a legitimate reason for securing their network, and have discussed options accommodating other stake-holders who might be inconvenienced by improving their system's security. It sounds to me like the police are handling this sanely and fairly. What's the problem here?

This has happened in hundreds of jurisdictions, and its been going on for a dozen years. Some jurisdictions only encrypt special tactical frequencies used for emergencies, but most realize that as soon as they did that they needed the decryption capable radios for every officer and car any way, and there was not much saving leaving regular channels unencrypted. They bought the radios, why not use them.
Not having reporters and wanna-be-cops show up at every incident was sort of a side benefit in their eyes.
Why the press would expect to be "loaned" a radio is beyond me. The press never "loans" their confidential sources to the police.
Sig Battery depleted. Reverting to safe mode.
I'll accept the police having encrypted communications, the moment EVERY COP on duty has video and audio surveillance on their person at all times recorded on person, and rebroadcast to their squad car for preservation without tampering.
Short of that? No, you can't have encrypted communications.
It's not just trunked but P25, with encryption. P25 digital signals can be scanned with a modern higher end scanner specifically designed for P25. Trunktrackers will not cut it. There is regular and encrypted P25. Encrypted P25 cannot be decrypted by the scanners. You'd need 2-way radio that can connect to the radio system as a user on the system and have approval from the agency to allow you to hear decrypted radio traffic.
Some media and agencies do this, but it's not too common. The radios are rather pricey and leasing them out tends to make the agencies nervous and liable to pull the plug at any moment.
There are also methods to break the P25 encryption mainly based on sloppy key handling by the agency and ways to take advantage of sloppy practices by the officers.
Sig for hire.
The bigger question should be how much personal information with respect to those accused/victims/witnessing crimes is indiscriminately broadcast over police radio.
No, that is simply a very good argument for encrypting everything and never releasing details of any of it to the public.
I really don't see why "the media" should have access to confidential police information that Mr X of Y address has been questioned on suspicion of Z if it turns out to be a mistake and he is released without charge later. You only need Z to be "rape" or "possession of child pornography" and Mr X is in serious trouble, even if he is totally innocent.
To have a right to do a thing is not at all the same as to be right in doing it
They don't release that information over the air. They just don't, ever. They use KDT terminals in the car for any sensitive information like names, addresses, etc. The most they will usually EVER give over the air is a phone number or situation codes like "Signal One", "Code Black" or "10-8". If they can't use the data terminals, most of the cops have figured out that a cell phone is an easy way to keep things off the air and confidential, a lot of them use the phone to call their dispatch and discuss any sensitive information like the type mentioned above on a regular basis and hardly ever use their radios at all anymore. As they switch to digital and encrypted type communications, they actually are finding their radios more useful than before - due to the extra margin of security, they actually CAN safely discuss names, addresses, etc.
That said, my Cook County Sheriff here in Chicago has been running full-time encryption since they went digital about 4 years ago. A lot of smaller city agencies are also in the process of going digital and want full-time encryption, too. When they did this, the world did not stop, the media did not dry up and blow away - somehow they still report on crimes in a timely manner, but a bunch of scanner geeks and hams were pissed off. That was it, that was the sum total of the impact. Unfortunately, I'm one of the hams that used to listen in because it was interesting when there was no Ham traffic to listen to, but hey, life is short - there's a lot of other things to do and listen to elsewhere!
