The Detroit Police Department was the first to use an 'on the air' voice communications system in what year?

Explanation:
Two-way, live voice communication between dispatch and patrol units represents a major shift in police radio history. Detroit’s police department is credited with being the first to put an on-the-air voice system into operation, and that milestone occurred in 1928. This meant real-time voice transmissions from the station to officers in the field and back, a step beyond earlier telegraph-based or non-live methods. The other years reflect times before or after this pioneering implementation, but 1928 is the documented first use for Detroit.
