Some corrections officials are doubling down on training to prevent a possible terror attack. It's something Putnam County Sheriff Howard Sills and Macon-Bibb County Sheriff David Davis have thought a lot about in his department.

He provides training to corrections officers on detecting potential terrorists among the inmate population. Religion reporter Jack Jenkins of Think Progress also joins us to talk about whether extremism is on the rise.
