Believe it or not, there are many public safety agencies that actually respect the public's ability to monitor them, so don't make assertions that our hobby will be dead on arrival by next year because one person gives us a bad name. Something like this happens every year...
I would conservatively estimate that over 200 of our live audio feeds are actually provided by the agencies themselves, and we are also in talks with larger agencies in hosting feeds for them (they've reached out to us.) Yes, there are some hard core agencies with misguided approaches to encryption, but a majority of agencies still see the benefit of not encrypting general public safety operations.
Technology is evolving Lindsay. The newer systems make encryption not only easier but a part of the complete package. The Feds are pushing it the way they are pushing P25. It's only a matter of time. No it isn't going to happen overnight, but I am talking 10-15 years from now when newer more advanced wireless technologies such as P25 phase II, III, IV, LTE and IP make it's way down to public safety radio will scanners become pretty much a thing of yesterday.
I don't want it to happen, I enjoy the hobby part of it as much anyone else including you. As a telecommunications professional I would be foolish to say "it's not going to happen ever" when in fact, slowly but surely it is. Newer digital systems offer greater security, both in access control and in the ability of the general public with affordable hardware and software to intercept. The Motorola iDEN system will be 20 years old in 2013, that's not far off- and to this day no commercial scanning equipment is available to monitor iDEN traffic, nor is it practical, by the very nature of a cellular topology listening in is not only difficult, it's futile.
P25 phase I is already on it's way out to make way for the next generation of Phase II gear. Motorola is expanding their APX line with new radios which are targeted to replace their Astro 25 line, they are proud of these products (as they should be, the APX is a superb product) and the next generation Phase II is right around the corner.
I don't want it to happen, but make no mistake, that is the future. It's only a matter of time, and it will happen sooner than we may like especially in larger cities where funding is not an issue.
