Andrew, you are right. I know that the chief took the job with the contractual understanding that he would be allowed the time off for his planned vacation. That was not mentioned in any of the news reports. Another item not reported, was that temporary coverage was arranged for his absence but the city was not willing to accept the requirements. Namely travel expenses to and from the island for the officer.
The other officers left mainly because they were being jerked around by the city. Also not mentioned in any reports.
