The County Sheriff and Police Departments
Sheriffs are elected by their constituents and have authority over their county. Police officers only have authority in their municipalities or city. Police officers are selected by application and their abilities in the academy. The county sheriff has many duties and responsibilities for the county they oversee. They are responsible for civil enforcement, such as evictions, divorce papers, subpoenas, and tax collection.
Some of their most important responsibilities are the management of the courts, jails, and courtroom security within their county. They are also accountable for the custody and care of prisoners while supervising the operations of the county jail. They handle many day-to-day administrative tasks. Examples include reviewing activity logs, evidence, budgeting, and investigations.
Sheriffs also perform many tasks that regular police officers normally do. They can give tickets, work traffic control, place people under arrest, and work with schools as a resource officer. Their more serious roles can include investigations into homicide, narcotics, and traffic accidents.
Cooperation between the county sheriff and the police department

The sheriff department will often have to cooperate with police officers in their jurisdiction. They help with the police hiring process and have the authority to make changes to the hiring process.
Depending on the size of the police force, the county sheriff will provide backup for the police departments and vice-versa. The sheriff department also processes things like paperwork and evidence for police officers. They will transfer cases between municipalities and borrow resources from the other, like K9 units.
The ways the departments work together will greatly depend on a few factors. Depending on the size of the county and police force, the sheriff department may have to do what is considered “beat cop” police work. This includes tasks like traffic stops, patrolling the city limits, and help with accidents. The cooperation between the departments is necessary and keeps the city safe.
