Used to be that Hendricks County's law enforcement talkgroups on SAFE-T were unencrypted except for the "32P-HQ" talkgroup, the SWAT TG, and the countywide drug task force TG. All of the law enforcement officers were pretty well trained to go to the HQ TG when they needed a records check. And, they used their MDTs quite a lot for records and other sensitive info.
But, someone decided that wasn't good enough. They encrypted all law enforcement TGs in the county. That said, I have occasionally heard in-the-clear radio traffic on 32P-DSP since the switch to encryption.
