Secret police
I suspect that what you are experiencing in Newfoundland is what I've been experiencing here in the Halifax Region, which encompasses a lot of RCMP talkgroups as well. The last time you heard any police transmissions was the last time. We now have SECRET POLICE. They will rationalize this new wrinkle by citing that the criminals and the drug dealers have scanners too and this is the price the legitimate, law abiding scanner owners must pay for a stable society. BS, I say ... the real reason is they don't want ANYONE, including the media, to know what they're up to. When a police force operates under a cloak of secrecy to this extent, I think it's time we all should start looking over our collective shoulders. The police had been using cell phones for communications that might tip the bad guys or compromise undercover personnel, so no one can convince me this level of security is necessary in a free and open society. I know in my area, I've heard disparaging remarks about media being on the scene ... law enforcement apparently doesn't like this at all.
Police, and especially the RCMP, have proven why they don't like people to know what they're doing and where they're doing it ... or, has everyone forgotten what was done to the Polish man who was killed in Vancouver Airport? People with scanners might be, ... could also be carrying cameras ... many of us have photography as a hobby and I have freelanced photos in the past. Police don't like people with cameras because facts sometimes "conflict" with the explanations they are prepared to give the public. Now , perhaps, you know why you will no longer hear any police calls on your scanners.
