I have been a firearms instructor, and have taught a lot of people how to shoot defensively with handguns, shotguns, and rifles. For a few years of my life, darn near every weekend was spent at the range. I started out as an assistant for some extremely experienced teachers and I also had the opportunity to be trained by some of the most accomplished firearms experts in the world. The man I stole most of my curriculum from was a Lieutenant Colonel in the Army Special Forces, turned federal agent SWAT team commander. I took classes in everything from wound ballistics (10 hours of looking at autopsy slides) to high-speed cool-guy door-kicking stuff. I’ve worked extensively with military and law enforcement personnel, including force on force training where I played the OpFor (i.e. I got to be the bad guy, because I make an awesome bad guy. You tell me how evil/capable you want me to be, and how hard you want your men to work, and I’d make it happen, plus I can take a beating). Part of this required learning how mass shooters operate and studying the heck out of the actual events.I am now a professional novelist. However, before that I owned a gun store. We were a Title 7 SOT, which means we worked with legal machineguns, suppresors, and pretty much everything except for explosives. We did law enforcement sales and worked with equipment that is unavailable from most dealers, but that means lots and lots of government inspections and compliance paperwork. This means that I had to be exceedingly familiar with federal gun laws, and there are a lot of them. I worked with many companies in the gun industry and still have many friends and contacts at various manufacturers. When I hear people tell me the gun industry is unregulated, I have to resist the urge to laugh in their face.I was also a Utah Concealed Weapons instructor, and was one of the busiest instructors in the state. That required me to learn a lot about self-defense laws, and because I took my job very seriously, I sought out every bit of information that I could. My classes were longer than the standard Utah class, and all of that extra time was spent on Use of Force, shoot/no shoot scenarios, and role playing through violent encounters. I have certified thousands of people to carry guns.I have been a competition shooter. I competed in IPSC, IDPA, and 3gun. It was not odd for me to reload and shoot 1,000 rounds in any given week. I fired 20,000 rounds of .45 in one August alone. I’ve got a Remington 870 with approximately 160,000 rounds through it. I’ve won matches, and I’ve been able to compete with some of the top shooters in the country. I am a very capable shooter. I only put this here to convey that I know how shooting works better than the vast majority of the populace.I have written for national publications on topics relating to gun law and use of force. I wrote for everything from the United States Concealed Carry Association to SWAT magazine. I was considered a subject matter expert at the state level, and on a few occasions was brought in to testify before the Utah State Legislature on the ramifications of proposed gun laws. I’ve argued with lawyers, professors, professional lobbyists, and once made a state rep cry.
