After looking thru a motorola catalog we had at work, I'll tell oyu what I know about Police Digital comms...
It seems that most of the MDT's in the cop cars are running 4800 bbps or 9600 bps with some kind of sceme called MDC if that helps you. I do konw that it is not the regular old AX-25 that they use...although some agencies, ie: PC Beacn FL polic,e looked like they were using little Henry TNC's with radio schalk laptops....so you never know...sdepends on the agency.
