Unfortunately my city dropped our 10-CODES about 2 years ago for the perceived plain language mandate that had been repealed. Now, a dispatcher will just reply, so and so is wanted, and the subject who I just ran looks at me to see if I am as ready to catch him as he is to run, oh well.
As mentioned before, everywhere has their own learning curve. When coming to my town you need to quickly understand the following: SO, CRT, ERIT, ACSP, CSP, MedCOM, WKU, CSX, KSP, KVE, LINK, NCIC, PS1, PS1, ACSU, CCSU, PeperBall, APO, MPO, District 10, 20, etc. and countless other abbreviations unique to our area. We used to have a county wide 10 code system, but it was scrapped. I agreed with many of the codes going by the way side, but many need to remain the same for brevity and uniformity. For example we used to say 10-9 for repeat. Now, many officers will say re-advise. But one of our Majors does not like that so we struggle to come up with something to replace it. What I have found is that codes often are void of specific meaning, they can be plural, singular, passive, in a future tense or anything that the situation needs. It is more difficult to think of what you need when you feel the need to make what you are saying make since in a verbal form.
Thanks for letting me vent.
