He'd be happy to have you. The Maricopa County Sheriff's Posse is one of the most active in the country. There is a mounted unit, jeep unit, EMT unit, airplane unit, mountain search & rescue unit, ham radio unit, etc. They patrol malls and sporting venues, look for fugitives and missing persons in the desert, and are called out for any kind of emergency. You can even get qualified to carry a pistol on-duty.
