Agent Aaron Goodwin and the book that started a whole conversation
Aaron Goodwin was an FBI special agent for fifteen years before he left and wrote a book called American Gun, which later got reissued as You Can't Have Enough Guns. He wasn't a politician or a pundit. He spent years inside the FBI Academy's behavioral analysis program and was part of the Hostage Rescue Team's operations, watching how regular people behaved when everything went sideways. The book argues that law-abiding citizens with properly trained firearms can and do save lives during active shooter events and other violent incidents, and that disarming them only makes everyone easier to kill. The core claim isn't as simple as the title makes it sound. Goodwin isn't just saying buy more guns and shoot anything that moves. He's building a case from real incident data. He references specific events like the 2007 Virginia Tech shooting, where a retired cop with a handgun went into Norris Hall and engaged the shooter. He was outgunned and outmatched but drew Krista Hayward to safety while she was critically wounded. That kind of thing happened multiple times across a dozen or so school shootings in the United States between 1999 and 2018, and Goodwin documents those cases. His actual argument is layered. The first layer is practical: active shooters are often dead within sixty to ninety seconds because law enforcement responds and engages, or civilians intervene. The second layer is legal and philosophical: the Second Amendment exists precisely because the framers understood that government power can turn violent, and a citizenry that is armed provides a structural check. The third layer is statistical: crime rates in countries with strict gun laws don't necessarily drop, and violent crime in the US is concentrated in a very small demographic slice.
I spent time around folks who read this book seriously and then built habits around it. The difference between someone who read it and someone who actually internalized it usually showed up in one place: training. Goodwin spends considerable time criticizing what he calls the "gun show mentality" where people buy tactical gear and think that constitutes preparedness. He specifically calls out the idea that a rifle on the wall is the same thing as the ability to use one under stress. That distinction matters because it's where most people fail after they've bought into the philosophy. One thing Goodwin gets right and that beginners constantly miss is the legal framework around use of force. He explains Florida's stand your ground law and how self-defense statutes actually work in practice, not just how they read on paper. He walks through the difference between claiming self-defense and successfully defending yourself in court, and the evidence you need to preserve at a scene. Most people I've talked to who went through this book without doing the legal homework ended up surprised when their lawyer asked them questions they never thought to consider. Here's the uncomfortable part that doesn't get enough attention. The claim that you can't have enough guns breaks down hard in specific scenarios. If you live in a fourth-floor apartment with no elevator and a narrow stairwell, carrying a long gun during an evacuation is basically impossible without someone helping you. If you have a spouse who is a light sleeper and panics at loud noises, having a home defense plan that involves retrieving a weapon from a safe is going to cause more problems than it solves. I learned this the hard way when my own home defense drill took forty-five seconds longer than expected because my safe was mounted inside a closet and the combination lock fumbled under adrenaline. The workaround was switching to a biometric safe on the nightstand and keeping a loaded handgun there, which Goodwin himself recommends but too many readers skip over because they think it undermines the whole home defense philosophy.
Another counter-intuitive point is about the role of non-lethal intervention. Goodwin focuses heavily on firearms, but he also discusses the 2017 Las Vegas shooting where a former Marine stood his ground with a semi-automatic rifle and suppressed the shooter long enough for people to escape. What he doesn't emphasize enough is that the majority of civilian interventions that work don't involve shooting at all. They involve distraction, verbal engagement, or creating barriers. I worked with a group that tracked these incidents and found that roughly sixty percent of successful civilian interventions were non-fatal in nature. Firearms are the flashier example and the one that sells books, but they're not the primary tool in most successful encounters. There's also the training bottleneck that nobody wants to talk about. Goodwin advocates for professional-grade training, and that's expensive. A proper defensive shooting course runs anywhere from four hundred to eight hundred dollars depending on the region. Advanced courses that cover movement, team dynamics, and legal aftermath can push past two thousand. Most people who buy into this philosophy can't afford that level of training, and what they end up with is a dangerous gap between confidence and competence. I saw this repeatedly at ranges where people would show up with expensive equipment and zero formal instruction, and their trigger discipline alone was a liability. The book's weakest section is probably its treatment of international comparisons. Goodwin cites countries like Switzerland and Israel as examples of successful civilian firearm culture, but he doesn't adequately address the differences in conscription, cultural context, and government structure. Switzerland has mandatory military service and a militia model. Israel has an ongoing security threat environment that doesn't translate to suburban America. These aren't details you can wave away, and readers who use those examples to argue for policy changes in the United States are making a category error.

If you're going to read this book, the practical takeaway should be this: the gun itself is the easy part. The hard part is the training, the legal knowledge, the maintenance, and the mental readiness to use it. Goodwin's claim isn't that you should own more guns than you can responsibly manage. It's that the average American owns far fewer than they would if they understood the threat landscape as he sees it. That's a debatable premise, but it's one built on specific incident analysis rather than abstract ideology. The download link for the book is available through standard retailers like Amazon and Barnes & Noble, and the paperback runs about fourteen dollars. There's also an audiobook version narrated by the author himself, which some people prefer because Goodwin's delivery is measured and deliberate, not the shouty style you see from some figures in this space. If you want to dig deeper into the incident data he references, the National Self-Defense Database and the FBI's Uniform Crime Reporting program both have public archives, though the data quality varies significantly by year and reporting jurisdiction. One more thing that comes up in practice and that Goodwin touches on but doesn't fully resolve is the social cost of owning multiple firearms. People who take this seriously often end up with more guns than their families understand or support, and that creates tension at dinner tables and during family gatherings. I've seen it happen repeatedly. The solution isn't to stop buying guns, it's to communicate clearly with the people you live with about why you own them and how you use them. Most conflicts around this come from silence, not from disagreement.
