Generally revise local law enforcement laws

This bill updates Montana's laws governing local law enforcement services for cities and towns, clarifying how police departments are organized and funded. It allows smaller third-class cities and towns to contract with county law enforcement agencies instead of maintaining their own police departments, while requiring municipalities to pay for sheriff-provided services. The legislation establishes a dispute resolution process where the Montana State University local government center mediates price disagreements between cities and sheriffs, with costs shared equally between the county and municipality. Additionally, the bill removes previous unfunded mandate requirements and defines who qualifies as a sheriff for these purposes.
