Is this the same case where someone in the fire department bought used radios for his department and programmed them himself because of a funding crisis? Or am I mixing things up?
I really wish we knew more: was "compromising... the secure system" using encryption keys they weren't supposed to have, or merely using a trunked radio system without permission? Anyone in Michigan know if you can get the transcripts of court decisions online?
As a taxpayer, I have a right to listen to any trunked radio system I choose, it's paid for with my money, so it falls under 'property rights' as well, as does driving these days, so if I choose to load up a radio with the entire fleet map, so be it.
By that logic, don't you have 'property rights' to top-secret military secrets? While trunked radio system information is obviously not the same as nuclear secrets, the logic is still the same.
next people will be saying "you cant inhibit someone elses radio, that would be illegal and they could sue you for damaging their property". Oh wait.. nevermind.
Not only are you not causing physical damage, but you're merely
asking the radio if it would, please, inhibit itself, and the radio complies.

I wonder how the system key thing would hold up If you used lab, which does not require a key to work.
I know Depot is considered a proprietary trade secret or the like. Is Lab the same way?
someone, somewhere, needs to produce the aforementioned scanner.. maybe even Piexx-style on a Maxtrac or Spectra platform.
Couldn't someone, conceivably, take one of the aforementioned radios and hack the innards (hardware) to completely disable its transmit ability? Then you'd essentially have an ASTRO Spectra 'scanner' that
couldn't affiliate with the network if it tried.
Is the controller accessible via the internet?
Couldn't it be, conceivably? Surely you can't just pull up
http://www.MyCounty'sTrunkedSystem.com/SecretAdminPage, but isn't it conceivable that some management functions can be done via VPN, rather than someone having to physically access the controller all the time?
And I think you could argue that, by virtue of being connected to a radio, it's not 'closed.'
the data would not be readable through Linux, Winblows or Redhat Etc...
My knowledge of TRS controllers is only slightly above nill, but if they're running Solaris as was described, it's 100% feasible that their data
can be accessed from any of those. (Unless they're running a Sun-proprietary filesystem like ZFS...)
They also have no IP address to locate said controller via the internet as well
When I first turn my computer on, it doesn't have an IP either, until my DHCP server gives it one. It's still a computer on a network, though.
