Security specialists have confirmed: glass remains the most vulnerable point of a religious building. Whether it's ancient stained glass or modern windows, a simple weapon is enough to shatter its protection. Joe Bockheim, a practicing Catholic and head of a company specializing in glass reinforcement, explains that using protective films or special panels can slow the impact of a projectile, sometimes even stopping it. These solutions are already used in schools and some churches.
Thomas Mynsberge, a former member of the Michigan SWAT team, confirms that these impact-resistant films can reduce the lethality of bullets fired from a handgun. But against high-velocity rifles, like the one used in the Minneapolis tragedy, only a one-inch thick polycarbonate panel secured in the frame can offer true resistance.
The Providential Role of Locked Doors
If the carnage in Minneapolis was not even worse, it is because the church had made a habit of locking the doors once Mass had begun. The local police chief, Brian O'Hara, acknowledged this: this act likely saved dozens of lives, preventing the shooter from entering the sanctuary. Remaining outside, the attacker cowardly fired through the windows without even seeing his victims, striking at the height of the pews where the children were seated.
Technical but Costly Solutions
Security companies explain that the safety film, typically made of polyester, costs between $20 and $25 per square meter. This is a significant expense for many parishes, often already facing financial difficulties. For example, installing film on eight glass doors and their side panels in a Michigan church cost about $2,500. But switching to thick polycarbonate costs fifteen to eighteen times more, an expense that is difficult to envision for most communities.
David Carson, a specialist in glass protection, recalls that the film was first designed to delay intrusion by sledgehammer or crowbar. Its role against bullets is limited, but it can slow their speed, buying time for those present. Polycarbonate, on the other hand, literally holds the projectiles as if they were absorbed in a gelatinous material.
However, even the best physical protections are not enough. As some experts acknowledge, true security must include other means, including the presence of armed men to defend the faithful.
The Responsibility of Catholic Communities
Brian Eaton, a police officer and founder of a Catholic fraternity in Arizona that trains parish ushers in security, emphasizes that it is better to install a protective film, even if it doesn't stop all bullets, than to do nothing. Every delay inflicted on an attacker can save lives. He insists: if full armor is unattainable, a minimum of reinforcement remains essential.
For Carson, a former physics professor, church leaders must take the issue more seriously: the targets are known, the means exist, but awareness is too low. Tight budgets should not serve as an excuse for inaction. The danger is real and must be anticipated.
A Societal Problem Above All
Beyond the technical aspects, Joe Bockheim points to the heart of the problem: if we are reduced to discussing bulletproof films for our sacred stained glass, it is because American society is sick. He concludes bitterly: "I want us to fix our people, not our windows." This observation is profoundly Christian: no human measure will replace the conversion of hearts and the return to God. The stained glass windows of churches, symbols of divine light, should be doors of beauty and not flaws through which barbarism enters.
