The O'Connor layover agreement was instituted by John O'Connor shortly after his promotion from St. Paul detective to chief of police on June 11, 1900. It allowed criminals to stay in the city under three conditions: that they checked in with police upon their arrival; agreed to pay bribes to city officials; and committed no major crimes in the city of St. Paul. This arrangement lasted for almost forty years, ending when rampant corruption forced crusading local citizens and the federal government to step in.
