Police Encrypt Radios To Tune Out Public

Hugh Pickens writes writes "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 and although law enforcement officials say they want to keep criminals from using officers' internal chatter to evade them, journalists and neighborhood watchdogs say open communications ensures that the public receives information as quickly as possible that can be vital to their safety. 'Whereas listeners used to be tied to stationary scanners, new technology has allowed people — and especially criminals — to listen to police communications on a smartphone from anywhere,' says DC Police Chief Cathy Lanier who says that a group of burglars who police believe were following radio communications on their smartphones pulled off more than a dozen crimes before ultimately being arrested. But encryption also makes it harder for neighboring jurisdictions to communicate in times of emergency. 'The 9/11 commission concluded America's number one vulnerability during the attacks was the lack of interoperability communications,' writes Vernon Herron, 'I spoke to several first responders who were concerned that their efforts to respond and assist at the Pentagon after the attacks were hampered by the lack of interoperability with neighboring jurisdictions.'"

The system uses the frequency band of 380-400 megahertz, which is lower than GSM. Due to the lower frequency band fewer base stations are needed. Digital VIRVE is encrypted, unlike its analog counterparts, and it has unified all previous authority networks into one network. The network makes it possible to transfer pictures and the same digital services as the GSM network. Furthermore, the network has a group call service that enables fast and efficient communication in a group of users. The expected number of clients in the network is 50,000. In July 2009 the number was 31,000. The power of the base stations is set to 25 watts, in vehicular devices it is 10 watts and in portable devices 0.5—3 watts.
      The network is separated into groups that can be modified in according to the needs of the operation at hand. The network is used by security officials: the police, rescue services, customs, border guard, social- and health department and the Finnish Defence Forces. Authorities can also allow access to the network for other personnel separately for a limited amount of time, under contract or limited to certain events. VIRVE is controlled and upheld by Suomen Erillisverkot Oy (State Security Networks Ltd.), which is owned by the State of Finland in whole.

Both Motorola and Hytera offer single-site trunking, wich are "almost but not quite" compatible, and multi-site single-channel working where both timeslots can be used on repeaters linked across a network.

One officer bragged to colleagues he arrested Rachner because he “acted edjumicated.” Rachner filed a complaint with the Office of Professional Accountability, the civilian-run oversight organization of the Seattle Police Department. Immediately after he filed the complaint, the city filed obstruction charges against Rachner that were later dropped because the prosecution lacked proof. Rachner received one dash-cam video recorded from a police cruiser’s dashboard camera during his criminal case but learned of six others that police refused to release. Rachner sued the Seattle police in 2008 for covering up the existence of the six other videos from the night of his arrest and other records pertaining to his case. He won a judgement against them in 2010, but filed a subsequent lawsuit on Oct.6, 2011, for false arrest, “spoilation of video evidence” and “malicious prosecution.” According to the Seattle Post-Intelligencer, the Seattle Police Department is currently under federal investigation for not releasing video evidence from dash-cams when requested.

      As someone who just recently was in a position to take advantage of municipal emergency services, I will state FLATLY that I could care less about encryption of such traffic even when the patient involved was me. Before the local and state agencies started encrypting everything under the sun (and we allegedly do our government "in the sunshine"), I routinely monitored such communications, and it has never been policy to broadcast essential personal details over the public service airwaves. However, it has been policy to record everything on the police, fire and rescue channels for decades, so it it a matter of record if you are privileged enough to get access to the records. Usually it has been sufficient for units to get into physical contact before going into anything sensitive, although cell phones now mean that even that isn't always necessary.

      The Communications Act of 1934 was a common-sense law. You could listen to anything. But if it wasn't a public broadcast, you kept your mouth shut. News agencies were just as much bound by that restriction as private citizens were. And news agencies, even in these diminished times, generally show enough respect to not go indiscriminately releasing sensitive information no matter where they got it from.

      One of the first steps on the downward trail from the Land of the Free to Patriot Act USA to me has always been when the cellphone companies ganged up and amended the original Communications Act to for the first time make it actually illegal to receive certain frequencies (lots of luck, they tended to bleed over). All this encryption is just the latest symptom of dividing the USA up into Us (Civilians) versus Them (Government), with Them operating out of sight with minimal oversight.

      There are certain communications that absolutely should be kept private. But relatively little of them. I've always felt that the ability to hear my taxes at work on the public safety frequencies gave me a better feel for the organization and operation of my local government. And, admittedly a certain sympathy for the police department, since most non-emergency calls seemed to involved people who were either drunk or crazy.

When in "emergency response mode" eg responding to accidents/hit-n-runs it operates in "clear" mode which allows for all cops, fire and paramedics to be able to communicate on the same or all channels.

    Well, I'm currently installing P25 systems in different counties -- and I also think we are moving toward a police state -- but I actually don't think the motive here is to hide communications. Most agencies we have converted are not using encryption, though the scanners are expensive. Most seem to care less about being able to encrypt.

    I think they were sold a buzz word. The systems cost a fortune. Due to the nature of digital radio, they work well, or not at all. If you work for the city water system, that's fine. When you work for the police, not working at all is a huge problem. Several firefighters were killed somewhere up north because nobody heard their calls for help.

    To get radios with federal grant money, the radios have to be P25 compliant. However, there is zero law that says they have to be used in digital mode. All the radios work in analog mode. All the systems we have put in will work in digital and analog mode. But no matter what the complaint of the new systems are, they can't reach over two inches and talk in analog. Why? Because it isn't a buzz word. I honestly don't think it has a thing to do with anything but that. It would almost be funny if the radios didn't cost hundreds of dollars more than their old radios.

    See also: Google about the planned nationwide 700 Mhz system for public safety. It was falling through the cracks but Senator Jay Rockefeller is now trying to get the project going again. The Rockefeller family has a lot of power in Motorola. Who wants to guess how much money he/his family is probably getting in a round about way through Motorola.

    This isn't about public safety. This is about multimillion dollar deals to enrich the same old people...in a country that is flat broke.

    Then all this talk of interoperability (which I am thinking more of it as a bankrupt expression these days), but encryption not helpful in that regard unless you have everybody using same key (which doesn't seem to make much sense).

    Regarding cost, I am seeing public safety agencies laying off cops and firemen and/or cutting pensions. Then these companies are pushing new radio systems which are ***very*** expensive. Sorry I don't buy that encryption is lowcost these days, kind of like cellphones that advertise lowcost but they will sock it to you with fees and locked-in monthly plans.

    And now this interoperability thing, I think it is industry driven to make lotsa money by bleeding govt agencies for whizbang systems with short life like cellphone apps. Talk to a regular beat cop or fireman, interoperability... what does that mean? The cop wants to be able to talk to dispatch and talk to other officers in his department. The fireman wants clarity and versatility (meaning be able to scale up or down depending on the ICS). For multi-dept response, firefighters have established mutual aid frequencies (fire white, yellow, blue). Occasionally a senior police officer may want to talk to another department, and if they can't use BAYMACS or CLEMARS, they can use the Raytheon ACU-1000. Or use a cellphone or some other means at the ICS command post. We all hear about communications breakdown during 9-11 but also realize NYC did not use ICS and there is a city ordinance that prohibits chief of police and chief of fire to meet the mayor at same time. Incredible as it sounds, maybe they straighten themselves in past ten years (I doubt it), I remember seeing footage on news of several NYC police and firemen in a large fist fight. This occurred some time after the 9-11 attacks and they had to reduce rescue/recovery staff at ground zero (virtually dead bodies been recovered). Some did not want to leave and return to normal duties, others insisted they do so, high emotions resulted. OK, I have to admit I haven't followed up with this story but I could only think, good thing my city doesn't have such a rife between fire and police (and their dispatch offices are right next to each other, instant interoperability and their sneakers don't need software).

This turned out to be an expensive exercise, with encryption rendering them useless

    The local media bitched and complained, but the biggest benefit is that you can have a car accident and not be swamped by tow-trucks vying for your business (and their 'gentle encouragements'). Oversight was achieved by having the clear-speech conversations all recorded at police HQ.

    As for interoperability, New South Wales police were up in Brisbane following the floods helping with law and order and they had their radios too. I guess it is just a matter of authorities sharing keys, or having a common key established up front. When Australian police forces went to New Zealand to help following the Christchurch earthquake in February they could use their radios. Tait Electronics and others set up programming stations and as long as the frequency coverage was there, the radios could be used.

    I use an 800MHz TETRA system with the State Emergency Service (like the US CERT, but state based) in Brisbane. This is not encypted (not all TETRA is), but there are very few scanners out there. Unfortunately this is incompatible with the 460MHz UHF system that the rest of the SES in Queensland use, so when we have teams from out of Brisbane we need to operate two networks. The text messaging feature of TETRA is very good for passing job information (flood evaculations, storm damage to houses, missing person details) that is not audible to people around you. Having an encrypted radio is not private if the volume on the speaker is very high and the media are within earshot.

    Everybody says they want interop but when the rubber hits the road, the fact is that everybody who has a radio system (or even a group of users on a system where they lease space) looks at their little corner of the world and theirs alone and they don't WANT to share it with users from other agencies and they also don't want their people on somebody else's system. In both cases, they lose control.

    As an example, I live in an area where about four different towns meet. They used to operate four different sets of radio channels which were technically compatible. Even when responding to a combined incident (a police chase, or mutual aid fire scene, for example), none of these four agencies would hop on the other agency's radio channels and coordinate directly. Instead they all routed traffic through their dispatch offices who then had to phone it across to the other towns because they weren't allowed to do anything else.

    Along comes P25 and all four towns migrated to a county radio system that covers the area -it belongs to none of the towns; they just lease space on it. Now, they ALL have the same radio gear, they could all theoretically have exactly the same programming in each radio or at least a group of common channels. In times where they need to coordinate, guess what happens? Yep. They each stay on their own channels and have the dispatcher phone across to the other towns, exactly the same as before even though it is actually easier now to do interop.

    They will not do it. PD Chief A does not want HIS officers talking to somebody else's dispatchers. Same for PD Chief B, the fire captains, and so on. They want their people to talk only to their people, and they don't want some other users coming on their system, using incompatible codes and signals (locally they are mostly compatible but with some oddities), and they mostly don't want to give up any control whatsoever. Their radio channels are theirs and no sharing.

    The whole idea of interop is to give up that precise control in the name of solving the problem faster/better. It sounds great on paper. In reality, it's a flop. If they have it, they don't want it and won't use it.

    Moving to encrypted P25 is not going to fix this -plenty of local areas already have P25 and still nobody talks to each other.

    There is one exception not far away from me where basically an entire county does have a working interop system where the local jurisdictions work with the county police all the time. Of course, they do this on conventional analog VHF with a booming glorious signal and it works very well. They don't even bother with trunking! Can you imagine this in 2011?
