Yes,  it was s contract between the City and the  State.  It ended with State Sheriffs  taking over airport during overtime abuse  by officers assigned to airport. The civil service positions for airport detail all went back to PD patrol slots. That won't  happen again,  City was happy to get out of that contract. Mayor,  City Council,  and Chief  lost control over officers assigned there because State airport authorities controlled command and officers  assigned there, CONTRACT  was the problem.
