I'm not looking for 'kiss my ass' answers. I'm just watching a movie and trying to find out and memorize new phrases. I've come across the abbreviation 'KMA' when the policeman informed the dispatcher that a couple of cops had died. He said: 'Two policemen ... KMA'(and nothing else). I couldn't find the meaning of this abbreviation while was surfing the net.
Since it was a policeman...
"KMA" was the FCC call sign prefix for police frequencies in Los Angeles.
You may want to refer to KMA 367 "An Unofficial History of the Los Angeles Police Department's Communications Division".
Likewise, other departments had other call signs (e.g. "KMG" was for the fire department).
In the context that was given, I don't think they meant KMA - end transmission. Jakoby was describing the two Officers down. I believe he meant to say KIA - killed in action.
Throughout the rest of the film they reference those Officers as killed, so I believe KIA is what they meant to transmit, but perhaps in the writing misused the acronym.
