But in May, the City of Mesa, a southeastern suburb of Phoenix, passed a measure to begin a three-year contract with the private prison company CoreCivic, a company marred in controversy and lawsuits across the country, becoming the first major Arizona city to use private prisons. Private prisons, or for-profit prisons, are privately owned facilities on government contract to house inmates.
