For this there are a couple of things that you ought to know; I will be quoting radio traffic between an officer and his dispatcher. 75 is a request made to see if there are local wants or warrants. 74 is results – generally translated as being negative. XX will represent officer’s unit number/name. Dispatch will be obvious.
XX-Dispatch; out with two suspicious characters dressed up as super heroes.
(Insert cricket chirps here.) (Dispatchers are cackling.)
XX-Dispatch; these two subjects are on their way home from a costume party. Put me out three minutes, community service transport. Batman and Superman.
Dispatch-XX; 10-4 10-6 (busy) community service en route Hall of Justice Batman and Superman 75/74 x (times) two.
Audible laughter erupts across station. Pregnant pause on radio.
