Even if they do go all MDT, there will still be plenty of interesting police activity to monitor (pursuits, bank robberies, etc.) as these operations will continue to use voice for obvious reasons. You just might miss out on some of the details of more minor incidents (barking dogs, parking complaints). But if the local PD in Carbon are like mine here in Berks, you can just go over to the local car-to-car frequency and listen to them read the MDT messages to each other!
