Jurisdictional talk is funny. Here is a small lesson on Phoenix and Maricopa County.
Maricopa County is 9,226 Square Miles and encompasses the fifth largest metropolitan area in the nation, Phoenix being the fifth largest city in the nation. There are many suburban cities and towns that make up this vast metro area. Phoenix is the largest, growing all the time, currently at 516 square miles.
The City of Phoenix Police Department's jurisdictional boundary is limited to the city limits of Phoenix. Police Officers, certified by the state certifying arm AzPost, are enabled to carry out the duties of a police officer in any portion of the state of Arizona. Jurisdictional boundaries, in this sense, bind the Court Systems of Phoenix (and the other municipal courts).
Maricopa County Superior Court is the Judicial Branch in which all criminal cases are tended to when they go beyond the municipal level. These courts are on the County Government Level and have jurisdictional boundary which stops at the geographical border of the county. Then, you have the state level of courts.
It is not fair to the sheriffs office to take the municipalities away from them in a crime statistic form. Without all the municipalities, you have only Fountain Hills, the Lakes, Sun City, Sun Lakes, Tonopah and other rural areas. The success of the Sheriffs Office, in the context of this tread, would be measured in studying the entire Valley's crime stats, municipalities included. Since all offenders go to the county jail system regardless of the city of their crime; it would only be right to measure MCSO's success by incorporating the entire valley's UCRs as a whole.
