[TheList] Encrypted radio

Mike,

What sort of patterns, responses and distinct environments are you interested in? How will you separate the traffic relating to crimes vs those relating to all the other things that police talk about?

If you need Crime patterns and response data for legitimate research there should be no problem in getting the information you need just by asking for it. It is not secret. However you will need to be quite specific as to what you ask for. (Getting the correct information will require time and effort to locate – fishing expeditions from people who don’t actually know what information they want  would not be welcome).  

However fact that you  even suggest that tracking the locations from which police radio comms originate could provide any relevant data about crime patterns or response tactics suggests that you probably need to learn quite a bit more about the subject before you start making information requests.

Re the legality of triangulation etc – suggest you read the legislation for  yourself it is quite clear what is and is not allowed:

·         Radiocommunications Act 1989 S 133A  <http://www.legislation.govt.nz/act/public/1989/0148/latest/link.aspx?id=DLM197387> Offence to disclose contents of radiocommunications   (Any Communications, not just “Private”)

·         Crimes Act 1961 S216B Interception of Private Communications (this is more serious, hence the 2 yr jail term)

Re the practicalities:  Give it a try and let us know how you get on. It’s theoretically possible, but in reality you don’t have a snowballs chance in hell of getting any useable information.

Cheers

Andy

Thanks for the advice. 

I was interested in patterns of crime, and patterns of police responses, in a series of distinct physical environments.

There's only so much information you can draw from the official crime stats, and I was thinking this might be a better way of analysing Police allocation of resources. I've just had another thought - I might be able to get a similar set of data if I use the Official Information Act to request movement from Police vehicles via on-board GPS.

As a matter of interest, would triangulation be illegal for any other radio transmissions, or just Police, or just "encrypted" Police?

Cheers

I define it as such:

It'd be a really really bad idea to try and triangulate any Police
transmissions - the question has to be asked, why would you want to
anyway?

It'd be a really really REALLY bad idea to tell anyone about it, or
even suggest to anyone you were doing such an act. That'd go as far as
asking asking above whether it could be done, or how it could be done.
If the Police found you were doing such a thing, you're likely going
to get charged under some act.

Its a question thats a lot safer not being asked.
