The mug shots of inmates are often available at the websites of county sheriff offices or county jails, such as the Maricopa County, Arizona, and Linn County, Oregon, sheriffs' offices. MugShots.com also publishes the booking photos of inmates from participating county jails across the United States.
In most states, mug shots are public record, notes the National Conference of State Legislature. Some online newspapers, such as the Des Moines Register, post the booking photos and arrest records from their coverage areas. The information provided by MugShots.com comes from the databases of police departments and the records of county sheriff offices or jail systems.
