A luncheon was held at the sheriff's office headquarters on west Jackson Street.
The academy is a chance for citizens to learn the day-to-day operations at MCSO and meet Sheriff Joe Arpaio.
"I think it's a positive experience," says Elizabeth Gregg. "I mean, everyone really gets to see what's going on... Because you know about the police, and the firemen, but you really don't get to know that much about the sheriff's department."
The citizens covered everything from criminal investigations to homeland security and SWAT.
