An old cop show set in LA. Not ATL, but fuck 12. Cops are called 12 in Atlanta because the drug unit cars are marked with “12”. That is some fun facts of the history of 12. This may be, but I don’t think ppl in Atlanta were the first, or only, to call police “12”. Definitely the first in the current context.
