Encryption is certainly easier in P25 environments, but just because the system is "state of the art" doesn't mean encryption will become the norm. The statewide system that is being built in Maryland is a mix of fully and partially encrypted law enforcement agencies. Fully encrypted agencies tend to be sheriff's departments in smaller (less populous) counties, while the state police keep their routine operations in the clear. Fire departments using the system use no encryption. The trend (at least in Maryland) seems that powerful (less accountable to oversight) sheriffs can dictate encryption, whereas organizations with more oversight (like police departments) use encryption where it is needed. For now. The state's Natural Resources Police that enforces hunting, fishing and boating regulations started out fully encrypted, but since they routinely interoperate with multiple agencies using multiple radio systems during SAR incidents found encryption a hindrance to effective communications. So now they operate in the clear.
