I met Gary at the Southeastern Writer's Conference. He has written two books about his experiences as a police officer. One is "Badge 149: Shots Fired" and the other is "Saints, Sinners, and Survivors".
I've purchased both books but have only read Badge 149. The books are a revelation of an honest man doing a difficult job. In my opinion, if you are a writer writing about law enforcement, his books are good in creating a more accurate world in perspective to law enforcement.
I have gone to Writer's Police Academy which is great. I highly recommend it. I'm still a book snob; so , a thriller has got to go a long way to move up in my tbr pile. But it is quite an event to create people and worlds.
I originally created a law enforcement character in a book that was not realistic and will disappear with the computer hard drive that stored it. I was glad to attend this conference. It broadened my view of law enforcement. Gary's book gave me a view of a regular cop doing his job and going home alive. Gary is very close to my original character. Except that character has some big hang-ups Gary does not have. lol
Anyway, I love non-fiction and this was great.
