I'm there with you T.L....
In my department, back a few years (it's changed since then), our call signs were set up as follows: Beat area, single man car=P, two man car=A, car number.... Normally I worked 1P12... then I ended up with a partner for a while, and became, by default, 1A12... over the radio it was "One-Adam-Twelve"...... We had a dispatcher that couldn't resist it, and each time we got a call, it was "One-Adam-Twelve, See the man....."
My then partner, now Sergeant, has an autographed photo of "Ofc. Reed", with an actual era LAPD badge, in a nice framed shadow box on the wall behind his desk..... The newer rookies look at it and ask if that is a picture of his father.... and that makes me feel really old..... they don't have a clue what Adam 12 even was......
