No, seriously, I was over there not too long ago, had their system programmed in, and about every 5 or so mins, I heard voice traffic from L.E. TG's coming across, loud and clear, sometimes just a sentence or so, sometimes entire conversations.
That's not "100%"
I agree it is an "encrypted system" (Thanks streemers) by design, but it is not "100% encrypted" if you can still hear "in the clear" traffic on an off the shelf scanner on it sometimes.
