It's a lesson they can't learn from just text books. It's the reason students from the University of Southern Mississippi's Arson Law Process and Procedures Class are rummaging through the ruins of Gulfport's old Wills Hotel. They're here to ask questions, and to uncover answers.
"They're actually getting their hands dirty," says Dr. Tom Payne, Associate Professor with the USM Administration of Justice Department.

A lesson learned and a final grade well earned.
