I've heard SBI here in Rowan County on both the Faith Mountain and Salisbury (Troop E HQ) sites on a number of occasions, matter of fact more times than not, running in the clear. It was what what some of us would consider to be "operational traffic" but nothing that seemed to be of a sensitive nature.
In my 396XT I've made it a point for the agencies I monitor on VIPER to add all talkgroups for that agency, encrypted or not, simply because you never know what you will hear on a day to day basis. Of course that's me, but it's served me well.
On a note dealing with Low Band VHF, Hi Band VHF, and UHF in NC........ Though yes we know majority of our state stuff has moved a lot to VIPER you still never know what you may hear. In my Low Band, VHF Hi, and UHF stuff I have those things programmed as well just because you never know what or who you may hear. But there again, that's just me and what works for me
