Idaho Church Attack Plot Highlights the Need for Armed Security, Emergency Planning, and Stronger Protection During Worship Services and Special Events.
November 11, 2026 | Church Security & Public Safety
An Idaho man has been sentenced to federal prison for plotting an attack against churches. The case is another reminder that houses of worship need to take security planning seriously, especially during services, holidays, and major events.
Idaho Man Sentenced in Church Attack Plot
On November 10, 2026, Alexander Scott Mercurio, of Coeur d’Alene, Idaho, was sentenced to 18 years in federal prison for attempting to provide material support to ISIS.
According to federal authorities, Mercurio planned to attack churches in Coeur d’Alene on April 7, 2024. The FBI arrested him on April 6, one day before the planned attack.
The plot involved multiple churches and a stated intention to cause mass casualties. Fortunately, federal investigators intervened before anyone was harmed.
The case illustrates why churches should not assume that an attack could never happen in their community.
A Quick Church Security Checklist
Church leaders do not need to wait for a specific threat to improve security. Here are several practical measures that can be implemented immediately.
- Hire professional armed security. Budget for trained, licensed where required, and properly insured armed security personnel during Sunday services, major events, and holidays.
- Maintain a visible security presence. Position uniformed security personnel near primary entrances and have them conduct exterior foot patrols when appropriate.
- Establish a church security team. Designate volunteers or staff members to assist with observation, communications, emergency procedures, and coordination with professional security personnel.
- Control building access. Keep unnecessary entrances secured during services while maintaining code-compliant emergency exits.
- Improve exterior security. Check parking lots, lighting, surveillance cameras, and areas where visitors approach the building.
- Establish reliable communications. Ensure ushers, church leadership, security personnel, and volunteers can communicate quickly when something requires attention.
- Develop an emergency response plan. Include evacuation, sheltering, medical emergencies, suspicious behavior, and procedures for contacting law enforcement.
- Train and practice. Conduct periodic security briefings and emergency drills. Make sure staff and volunteers understand their responsibilities.
These are basic measures, but they can make a significant difference in how quickly a church identifies a problem and responds to an emergency.
Church Security Should Be Part of the Annual Budget
Churches routinely budget for utilities, maintenance, insurance, staffing, and community programs. Security deserves consideration in that same budget.
A professional armed security officer can provide a visible deterrent, monitor activity around the property, communicate with church leadership, and respond within the scope of their training and authority when an incident occurs.
Churches should consider budgeting for security during:
- Regular Sunday worship services
- Christmas Eve and Christmas Day services
- Easter services and Holy Week
- Large conferences and guest-speaker events
- Community celebrations and festivals
- Special events that attract larger crowds
Not every congregation has the resources for full-time security. However, even a limited security budget can provide professional coverage during the busiest and most vulnerable periods.
Security should be planned and funded before an emergency occurs, not after.
Professional Armed Security and Church Volunteers Can Work Together
Many churches already have volunteer safety or security teams. These individuals often know the congregation, the building, and the daily operations better than an outside contractor.
Professional armed security does not have to replace those teams.
Instead, trained security officers can work alongside church volunteers, ushers, and leadership to establish a coordinated security presence.
The goal is to provide a welcoming environment while ensuring that someone is specifically responsible for identifying and addressing potential security concerns.
