What Every Concealed Carrier Should Know About Self-Defense Law (Straight From a Lawyer)
Most people who carry a gun every day have never sat down with a lawyer and asked, "Okay, but what actually happens if I have to use this?" They know how to draw, how to grip, how to keep a round chambered. Far fewer know what the law expects of them in the ten seconds before that becomes necessary, or the ten hours after.
That's the gap we wanted to close in episode 11 of Tulster Talks. We sat down with Joel LaCourse of LaCourse Law for a real conversation about the legal side of carrying concealed — not internet-forum legal theory, but the actual framework that determines whether a defensive use of force holds up in court. This post walks through the six areas we covered: stand your ground versus duty to retreat, castle doctrine, what to do in the immediate aftermath of a defensive shooting, gun-free zones, and reciprocity when you travel.
A quick note before we get into it: gun law is state law, and it changes. Nothing here is a substitute for knowing your own state's statutes or having a relationship with an attorney before you ever need one. Consider this the map, not the territory.
Stand Your Ground vs. Duty to Retreat
This is the distinction that shapes almost every other question on this list, and it's also the most misunderstood.
"Stand your ground" means that if you're somewhere you're legally allowed to be, you have no legal obligation to attempt to retreat before using force in self-defense — you can stand and defend yourself. "Duty to retreat" means the opposite: in the states that still follow this doctrine, you're required to attempt to safely withdraw from a threat, when a safe retreat is available, before resorting to force outside your own home.
As of 2026, roughly 29 states have stand-your-ground protections on the books by statute, with several more reaching similar outcomes through case law. Around a dozen states, including California, New York, New Jersey, and Massachusetts, still impose some form of duty to retreat in public. The practical difference matters most in the gray-area cases — the ones where you had an opportunity to walk away and didn't. In a stand-your-ground state, that choice is protected. In a duty-to-retreat state, a prosecutor can point to it.
The takeaway isn't "know the map of all fifty states." It's simpler than that: know the law of the state you live in, and if you carry while traveling, know the law of the states you're driving through. We'll come back to that in the reciprocity section below.
Castle Doctrine: What "Home" Actually Means Legally
Castle doctrine is the principle that inside your own home, you generally have no duty to retreat at all, even in states that otherwise require it everywhere else. The idea, going back centuries in common law, is that your home is the one place you shouldn't be forced to flee from an intruder.
Where it gets complicated is the definition of "home." Most states extend castle doctrine protections to your dwelling and, in many cases, your curtilage — the porch, the attached garage, sometimes the yard. Some states extend it further, to occupied vehicles or a place of business. Others draw the line tightly at the walls of the house itself. A few states also require that the intruder have entered unlawfully and that you reasonably believed you or someone else was in danger — it's not a blanket license to use force against anyone who sets foot on your property.
If you take one thing from this section: don't assume your state's castle doctrine covers your truck, your shop, or your yard just because it covers your living room. Look it up, or ask an attorney who practices in your state.
What to Do in the First Hour After a Defensive Shooting
This is the part of the conversation that tends to get the least attention in gun-owner circles, and it's arguably the most important. A legally justified shooting can still turn into a legal nightmare if you handle the aftermath poorly.
The general framework attorneys who work self-defense cases tend to recommend looks something like this: call 911 and report that you were attacked and had to defend yourself, stay on scene and cooperate with basic officer safety instructions, and then exercise your right to have an attorney present before giving a detailed statement. You are not required to walk investigators through a play-by-play in the adrenaline-soaked minutes after a shooting, and doing so is exactly when people misstate facts, use language that sounds worse than what happened, or say something a prosecutor can build a case around later. "I was in fear for my life, I'll cooperate fully, and I want my attorney present" is a complete sentence.
This is also the moment where concealed carry insurance or a legal defense membership stops being a line item and starts being the thing standing between you and $500,000 in legal fees, even when you did everything right. Even a fully justified shooting can trigger a criminal investigation, a grand jury review, or a civil suit from the other party's family. Having a plan — a specific attorney's number, ideally memorized or saved somewhere you can reach it in a crisis — is not paranoia. It's the same category of preparation as carrying the gun in the first place.
Gun-Free Zones and Prohibited Places
Every concealed carrier eventually runs into this problem: you're dressed, you're carrying, and you're about to walk into a building where that's not allowed. Knowing where those lines are drawn is as much a part of responsible carry as knowing how to shoot.
Federal law prohibits firearms in a specific, relatively short list of places: federal buildings, federal courthouses, the U.S. Capitol grounds, and school zones under the Gun-Free School Zones Act, with some exceptions for permit holders depending on the state. Everything beyond that is state law, and it varies enormously. In the years since the Supreme Court's 2022 Bruen decision, several states have significantly expanded their list of "sensitive places" where carry is restricted, adding categories like polling places, government buildings, bars and establishments that primarily serve alcohol, and various public gathering spaces. Private property owners can also restrict carry on their premises, and in many states, a posted sign carries real legal weight, not just a suggestion.
The practical habit worth building: before you carry somewhere unfamiliar, especially in a state you don't live in, spend five minutes checking that state's current prohibited-places list. It changes more often than most people assume.
Carrying Across State Lines: Reciprocity Isn't as Simple as It Sounds
This is where a lot of otherwise careful concealed carriers get tripped up, because reciprocity is one of the more misunderstood pieces of carry law. Reciprocity refers to whether one state recognizes a permit issued by another state. It is not a single national standard, it's a patchwork of individual agreements, and it can change with very little warning when a state updates its statutes.
A few things worth internalizing: your home state's permit might be honored in some neighboring states and not others, even ones that seem culturally similar. Some states recognize any out-of-state permit; others only recognize permits from states with certain requirements; and a handful don't recognize out-of-state permits at all, regardless of what you're carrying. Permitless carry (sometimes called "constitutional carry") in your home state does not automatically mean you can carry permitless when you cross into another state — many constitutional-carry states still require a permit for the reciprocity privilege to apply elsewhere.
Before any road trip, check a current reciprocity map for every state on your route, not just your destination. Laws change enough that a map you checked a year ago isn't a source you should be carrying a firearm on.
Frequently Asked Questions
Do I have to retreat before using deadly force in self-defense?
It depends on your state. States with stand-your-ground laws don't require you to attempt retreat before defending yourself, as long as you're lawfully present. States with a duty to retreat require you to attempt a safe retreat first, if one is available, before using force outside your own home.
Does castle doctrine cover my car or my front porch, not just my house?
It depends on the state. Many states extend castle doctrine to a home's curtilage (porch, attached garage) and sometimes to occupied vehicles, but the boundaries vary significantly. Check your specific state's statute rather than assuming.
What should I say to police after a defensive shooting?
Report that you were attacked and needed to defend yourself, cooperate with officer safety instructions, and then invoke your right to have an attorney present before giving a full statement. You are not obligated to give a detailed account on scene.
Can I carry into a business that has a "no firearms" sign posted?
In many states, a posted sign on private property carries legal force, and ignoring it can be treated as criminal trespass, separate from any question of self-defense law. Treat posted signage as legally binding unless you know your state treats it as unenforceable.
If I have a concealed carry permit, can I carry in every state?
No. Reciprocity between states is not automatic or universal. Some states honor most out-of-state permits, some only honor certain ones, and some don't honor out-of-state permits at all. Always check a current reciprocity map before carrying across state lines.
Do I need concealed carry insurance if I'm confident I'd never actually need to use my gun?
Legal costs after a defensive shooting can run into the hundreds of thousands of dollars even when the shooting is fully justified, because criminal investigations, grand jury review, and civil suits can all follow a legally clean self-defense case. Most attorneys who work this area recommend some form of legal defense coverage as standard preparation, not a worst-case extra.
The Gear Doesn't Replace the Knowledge
At Tulster, we spend our time thinking about retention, draw stroke, and getting a holster to disappear against your body so carrying becomes second nature. None of that matters if you don't understand the legal framework you're operating inside of. A good holster keeps your gun secure and accessible. It's on you to know when, where, and how the law allows you to use what's in it.
That's why we sat down with Joel LaCourse for this conversation, and why we'll keep bringing legal, training, and gear experts onto Tulster Talks. Watch the full episode for the parts of this conversation that don't fit neatly into a blog post, and if you're due for a holster upgrade, take a look at our IWB and OWB holsters while you're at it.
