The Layered Security Concept
When the temperature drops, you dress in layers. A base layer for warmth. An insulating layer for retention. An outer layer for protection against wind and rain. No single layer does the job alone — but together, they keep you safe in conditions that any one layer could not handle.
The same principle applies to security against active shooter threats. No single measure — not training, not cameras, not locks, not armed personnel — provides complete protection. But layered together, they create overlapping defenses that dramatically improve survival odds.
"Cameras document incidents, but deterrents like Bolo Stick keep threats out and buy time. It’s about creating layers of security."
— Bill Barna, Bolo Stick founder and 33-year retired police officer
Layer 1: Training and Awareness
The foundation of any security protocol is education. Programs like ALICE (Alert, Lockdown, Inform, Counter, Evacuate) have trained over one million people across 50 states. These programs empower occupants to assess a threat and choose the appropriate response: escape if possible, shelter and barricade if not, and fight as an absolute last resort.
CISA’s K-12 School Security Guide recommends regular drills conducted with local law enforcement to build muscle memory and procedural familiarity. Training alone saves lives — but training combined with physical barriers saves more.
Layer 2: Physical Barriers
An active shooter typically seeks to maximize casualties in the shortest possible time before law enforcement arrives. Most incidents conclude in five minutes or less. Every door that resists forced entry is a door that buys time — time for occupants to shelter, time for police to respond.
The ALICE lockdown protocol instructs occupants to barricade doors with furniture — desks, chairs, filing cabinets. This is better than nothing, but it is slow, physically demanding, and unreliable. Under extreme stress, the fine motor skills and physical coordination needed to stack furniture deteriorate rapidly.
Purpose-built door barricade devices solve this problem. The Bolo Stick secures a door against more than 4,200 pounds of force with a single action — insert the round peg into the round hole. No training. No fine motor skills. No heavy lifting. It works on both inswing and outswing doors and includes first responder master key access that supports fire-code compliance in most jurisdictions.
"SWAT officers spent 20 minutes trying to breach a door equipped with a Bolo Stick. They destroyed part of the door, but the device held."
— Bill Barna
Layer 3: Last-Resort Defense
If the first two layers fail — if training is insufficient and the door is breached — occupants are left with improvised defense. Throwing books, staplers, and office supplies at an armed attacker is a heavily lopsided engagement. Programs like ALICE address this with "Counter" strategies: movement, noise, distraction, and swarming.
Non-lethal defense products designed for classroom and office use — such as tactical-grade pepper spray devices mounted for quick access — represent an emerging third layer. These products provide a more effective defensive option than improvised projectiles while avoiding the legal, liability, and safety concerns of firearms in civilian settings.
The Math of Layered Security
The FBI’s Active Shooter data reinforces the urgency: 333 incidents and 2,851 casualties from 2000 to 2019. Through 2024, the threat continues with 223 additional incidents. Schools, churches, and workplaces remain the primary targets.
Each layer of security reduces the attacker’s advantage:
- Training gives occupants a plan and the confidence to execute it
- Door barricades deny the attacker access to rooms full of potential victims
- Defensive tools provide options if all other layers are overcome
One layer is better than none. Two is better than one. Three is better than two. Dress your security in layers.
