J.Tom Morgan has a lot of Facebook friends – more than 4,000 actually. Just about all of them are teenagers peppering him with questions about Georgia law. They want to know their rights and how to avoid getting into serious trouble. And the former longtime DeKalb County District Attorney is more than happy to let them know. Morgan has sold more than 27,000 copies of Ignorance Is No Defense, A Teenager’s Guide to Georgia Law, a self-published book that he speaks about at schools, community centers and just about everywhere else anyone will listen, in hopes of educating young people and their parents about Georgia law.
