There is likely to be interesting SAFE-T traffic in the Bloomington area today and tomorrow with the visit of Robert Gates, defense secretary (Secretary of Defense Robert Gates to speak at IU's 2009 Winter Commencement: IU News Room: Indiana University). There were plenty of IUPD and ISP cars around the Memorial Union today, and I heard traffic on 53-IUP-DISP and SW-MA-1 which seemed related. Would be interesting to know if any encrypted talkgroups are being used.
