SLER agencies
The primary ones are Highway Patrol.... Fish and Wildlife, FDLE, DOT and several others such as Investigators from Fire Marshal, Insurance, Attorney General, etc. etc. ... Its not a whole lot and really the Fish & Wildlife is probably the most interesting. FDLE has enryption and also there are a few task forces that are using the State system, and its 50-50 on encryption...
The nice thing about FHP is you know where the wrecks are faster than the traffic alerts and the highway warning system....
