Mike talked with David McCullough, of Central Alabama Firearms training, who conducts active shooter defense courses, and former U.S. Army Ranger Capt. Matt Bacik, who received a Bronze Star and three Purple Hearts fighting overseas and is the now the CEO of a company that among other things, helps entities overseas with security, to break down some of the most popular options.
