1. It's probably not too much of a secret who recorded it and/or made it available. First of all, there are several people in MB who are well known to the police and make such recordings on a regular basis. Besides that, the original post came from a Shaw internet account, which isn't exactly anonymous either.
2. Mostly all media agencies have either scanners or radios issued to them by the public safety agencies. This won't do anything toward encryption. If police didn't want media to know what is going on, they wouldn't issue media agencies receive-only XTS2500s, or even more, issue press releases.
3. I was the one who brought the clip to RadioReference as I posted the link to shaw.ca that I found on another forum. I don't think that's a bad decision that I made. First of all, it's radio comms related to a newsworthy incident, and this site is about radio comms. Second of all, regardless of what details are in it, it's unlikely to make an impact on the lives of the poor man's family. The injustice was done to their loved one, and whether it is reported or not, it still happened. I'm pretty sure that the victim's family isn't out trolling the Internet right now.
Having said all that, I can understand the RCMP's dismay at their comms being recorded and released without their permission. Many places here treat their comms as super-secret despite the fact it is inherently not so due to its technical nature, and have even convinced certain scanner enthusiasts to play into that game. Personally, I don't say anything on a radio that I wouldn't shout from a rooftop with a megaphone. I know there are thousands of scanner users who listen to me and my colleagues all the time. If it were my decision to make, I would be more upset at the agencies which treat open-air comms as private when they're not, instead of being upset at someone posting a clip of a radio transmission.
If you are against posting clips of radio transmissions, are you looking to eradicate live streaming scanners on the Internet as well? What about the "Breaking News" forums here where posters send out information on calls "as paged"?
It's just information. If it's not being used for improper gain, it's not violating laws, morally or legally.
Anyway, having said all that, the above are my opinions and are posted civilly within the rules of the forum. Please keep it clean and civil in here so we don't have to lock the thread.
