The Sheriff is a constitutional officer who assigned duties and limitations by statute. He is the supreme law enforcement officer within a speciific territorial jurisdiction.
You are correct.. however the reality in this situation is the continued annexing of "unincorporated" areas into the "city limits"... while I am not opposed to anexation it does present the problem of who provides law enforcement services to the city... the Police Department or the Sheriff... or in out case BOTH.. Our Sheriff has made it very clear that residents INSIDE city limits may request law enforcement services from their ELECTED head of Law Enforcement...
