If you hear gunshots, the response taught by federal law enforcement is simple in order and strict in priority: run if you can, hide if you can’t, and fight only if there’s no other choice. That’s what to do if you hear gunshots, and the sooner you commit to one of those three actions, the better your odds. The specifics inside each step are what actually keep you safe.
Run, Hide, Fight, in That Order
Run-Hide-Fight is the official protocol taught in federal active-shooter preparedness training. The three steps are prioritized: running beats hiding, and hiding beats fighting. You only move to the next step when the one before it isn’t possible.
Run
Getting away from the shooter is always the top priority. If you can see or figure out a clear escape path, take it immediately. Leave your belongings behind. If others nearby will follow, help them move, but don’t wait for anyone who freezes or refuses to go. Once you’re at a safe distance, call 911. Keep your hands visible as you run so arriving officers can see you’re not a threat.
Hide
When no safe escape route exists, find a place where the shooter is unlikely to find you. Lock and barricade doors with heavy furniture. Close blinds and turn off lights. Silence your phone completely, including vibration. If you’re with others, don’t huddle in one spot. Spread out along walls or hide separately, which makes it harder for a shooter to target the group. If you can, communicate with police silently through text messages or by placing a sign in an exterior window. Stay hidden until law enforcement gives the all-clear.
If you can’t speak safely but have phone access, dial 911 anyway and leave the line open so the dispatcher can listen to what’s happening.
Fight
Fighting is a last resort, reserved for moments when your life is in immediate danger and neither running nor hiding is possible. Department of Homeland Security guidance is blunt: commit fully and act as aggressively as you can. Throw objects, yell, and use anything nearby as an improvised weapon. Chairs, fire extinguishers, scissors, and heavy books can distract or disarm a shooter long enough to create an opportunity to escape or subdue them.
Was That Actually a Gunshot?
Fireworks, car backfires, and construction noises are frequently mistaken for gunshots, and the reverse also happens. A few patterns help.
Gunshots tend to produce a sharp crack. Most ammunition breaks the sound barrier, which creates a distinctive snapping sound different from the deeper boom of a car backfire or the drawn-out crackle of fireworks. Gunfire also tends to follow a deliberate rhythm or come in rapid clusters. Fireworks are more sporadic and often include whistling sounds, trailing sparks, or echoing pops. Car backfires sound rounder and more hollow, usually in evenly spaced pops tied to engine revving, and with modern vehicles they’re relatively rare.
If you’re genuinely unsure, treat the sound as gunfire and follow the safety steps. Law enforcement would rather respond to a report that turns out to be fireworks than miss actual shots because someone second-guessed what they heard.
How to Call 911
Wait until you’re in a safe location before dialing. Active gunfire is exactly the kind of immediate threat the 911 system exists for. When you connect with a dispatcher, speak clearly and cover these points:
- Your location: exact address, nearest intersection, floor number, or any landmarks that help officers find the scene.
- What you heard: how many shots, whether they were rapid or spaced out, and the last time you heard one.
- Suspect details: if you saw anyone, their clothing, height, build, and direction of travel. If they got into a vehicle, the color, make, model, and plate number if you can note it safely.
- Weapons: if you saw a firearm, the type if you can tell, such as a handgun or long gun.
- Injuries: whether you’ve seen anyone hurt.
Dispatchers are trained to pull useful information from callers under extreme stress, so don’t worry about being perfectly composed. Stay on the line if the dispatcher asks you to. They may update responding officers with what you say in real time.
Picking a Hiding Spot: Cover vs. Concealment
Not everything that hides you protects you. Federal training materials distinguish between cover, which can stop or deflect rounds, and concealment, which only blocks the shooter’s line of sight.
Materials that provide real cover include concrete pillars, brick walls, reinforced concrete, engine blocks of vehicles, and solid steel desks or filing cabinets. These are dense enough to stop most rounds.
Materials that only conceal you include interior drywall, cubicle walls, curtains, hedges, and hollow-core doors. A bullet passes through multiple layers of drywall without much resistance. A car door, despite what movies suggest, is not reliable cover either; the thin sheet metal and glass won’t stop rifle rounds. A thick wooden door might slow a small-caliber round but shouldn’t be trusted against anything more powerful.
Cover is the goal when you’re choosing a hiding spot. If cover isn’t available, concealment is still better than being in the open, because a shooter who can’t see you is less likely to target you. Just don’t mistake being hidden for being safe.
When Police Arrive
The first officers on scene have one job: locate and stop the threat. They will move quickly and may appear intense or aggressive. That is normal.
Keep your hands visible and empty at all times. Do not run toward officers, grab them, or point at things with objects in your hands. Follow their commands immediately, even if the instructions seem confusing or redundant. Move in the direction they tell you to go. If they tell you to get down, get down.
Officers arriving during an active situation may not stop to help injured people. Their initial priority is ending the threat. Medical personnel and additional officers follow behind to assist the wounded. If you’re sheltering near someone who’s hurt, do what you can, but understand the first wave of responders is focused on the shooter.
After the area is secured, officers will likely direct you to a designated staging area. You may be asked to stay and provide a statement about what you saw and heard. Your observations, even details that seem minor, can be valuable to the investigation.
What Not to Do
Some instincts that feel natural in the moment can get you hurt or compromise the police response.
Don’t investigate. The urge to look outside, peek around corners, or walk toward the sound is surprisingly common. Resist it. You have no way of knowing whether the shooting is ongoing, whether additional shooters are present, or whether the area between you and the sound is safe.
Don’t touch potential evidence. Shell casings, damaged property, and discarded items could be critical to the investigation. Moving or handling evidence can contaminate it or destroy forensic information. Leave everything where it is.
Don’t post unverified information. Sharing real-time speculation on social media about a shooter’s identity, location, or motive can cause panic, misdirect emergency services, and interfere with the police response. Report what you know to 911 and let law enforcement handle public communication.
Don’t interfere with officers. Even well-intentioned actions like trying to direct them or provide first aid in an unsecured area can be read as interference. The most useful thing you can do is stay out of the way, follow commands, and give clear information when asked.
If You Carry a Concealed Firearm
Responding officers don’t know who the threat is, and anyone holding a gun in an active-shooter situation is likely to be treated as a suspect until officers sort out what happened. The consistent advice from law enforcement trainers: holster your weapon and keep it concealed before police arrive. If you can’t holster it, set it on the ground and step away. Keep your hands visible and far from your waistband. When officers approach, move slowly, comply with every instruction, and tell them immediately that you have a firearm and where it is. Expect to be treated as a suspect initially. Stay calm and let them clear you.
Honest Reports Are Protected; False Ones Are Not
Reporting what you genuinely believe to be gunfire, even if it turns out to be fireworks, is the right thing to do and carries no legal risk. Deliberately filing a false report is different. Under federal law, knowingly conveying false information about a dangerous activity like a shooting can result in up to five years in prison. If someone is seriously injured because of a false report, the maximum jumps to 20 years. If someone dies, the penalty can reach life imprisonment.1Office of the Law Revision Counsel. 18 U.S. Code 1038 – False Information and Hoaxes State penalties vary but are universally treated as criminal offenses.
After It’s Over
Hearing gunfire, even if you’re never in direct physical danger, can leave a mark. The VA’s National Center for PTSD notes that common reactions to traumatic events include feeling jumpy at sudden noises, being unable to concentrate, intrusive memories, difficulty sleeping, and withdrawing from other people. Physical symptoms like a racing heart, stomach problems, headaches, and changes in appetite are also normal in the days and weeks afterward.2U.S. Department of Veterans Affairs.

Most people recover naturally over time. If these reactions persist, interfere with your work or relationships, or get worse instead of better, talk to a counselor or doctor. The ATF’s Victim/Witness Assistance Program provides support to witnesses of crimes investigated by federal agencies, including referrals for mental health counseling, emergency housing, and support groups.3Bureau of Alcohol, Tobacco, Firearms and Explosives.
