While no strategy is foolproof, a thoughtful, risk-based approach—combined with expert insights—helps create safer public spaces.

The recent tragic attacks in New Orleans and Las Vegas serve as sobering reminders of the vulnerabilities public spaces face and the devastating impact such events can have on communities.

As a security risk management professional, I’m often asked after incidents like these how public places—such as shopping centers, community gathering spots, or entertainment venues—can better protect themselves.

While it’s impossible to eliminate every threat, certain measures can reduce the chances of an incident or lessen its impact should one occur. Taking a risk-based approach to protecting public spaces helps implement the right solutions tailored to the unique needs of different locations and events.

Risk Profiles: One Size Does Not Fit All

Every location is unique. What works for a massive sports arena may not be practical for a small community theater.

To identify a specific site profile to address possible threats, and vulnerabilities, taking a “risk-based approach” helps to ensure that the security measures implemented are effective, sustainable, and appropriate to for a specific security budget.

Consider the venue: Is your venue a high-traffic spot in a major city, or a smaller location with fewer visitors? Are you near a major tourist attraction that draws crowds? Is the public profile of the location or event the topic of a potential news story if something tragic happens? All these factors influence how attractive a target the venue may be.

  1. Understand the potential threats: Common high-impact threats include active shooters, vehicle-based attacks, explosives or bomb threats, and edged-weapon attacks.
  2. Identify potential vulnerabilities: Are there large, open entrances that could be exploited? Do you have the ability to detect individuals carrying weapons? Are security protocols up to date? Is critical incident response plan well-drilled?

Considering these factors provides a clearer understanding of your risk profile and informs on the steps needed to help mitigate those risks.

As a risk management professional, I know that each unique risk profile requires tailored solutions. To provide the most effective strategies, I reached out to experts with deep knowledge in threat detection and mitigation.

Expert Insights: Monitoring, Assessing, and Mitigating Threats

Glen Kucera, president of Allied Universal Enhanced Protective Services, emphasizes the importance of intelligence analysis – understanding what people are saying about your venue or event.

“One of the keys to proactive threat management is monitoring open-source intelligence, from mainstream social media channels to chatter on the dark web,” he says. “Knowing what’s being discussed about your location, event, or even your organization’s leadership can help identify potential risks before they escalate.”

Modern security extends well beyond physical defenses. By analyzing information from social media, public forums, and dark web sources—within legal and ethical boundaries—organizations can better detect suspicious activity early, escalate concerns as needed, and make better-informed decisions about protective measures.

Threat Assessment and De-escalation in Public Spaces

Next, I spoke with Hugh O’Rourke, a risk management expert at Allied Universal, identifies early warning signs—often revealed through social media leaks or noticeable changes in behavior—and what happens once a potential threat is identified.

“Violence rarely happens in a vacuum,” he says. “Most attackers display warning signs—grievances, unusual behavior, or direct threats. A vigilant approach to monitoring these signs helps you to assess threats as you find them.

“Threat assessments are about asking two key questions: Is there a real danger? And if so, how can we mitigate it? Often, early intervention and respectful engagement can help defuse tensions before they escalate,” says O’Rourke.

Direct outreach and offering help also can be remarkably effective in protecting public spaces, particularly for someone in crisis or feeling unheard. In more serious cases, law enforcement involvement may be necessary. A formal process and well-defined team helps organizations  respond swiftly and responsibly to emerging threats.

Physical Security Measures for Public Spaces

No discussion about violence mitigation is complete without addressing physical security. Ty Richmond, president of event services at Allied Universal, outlines strategies for protecting against mass violence—such as vehicle rammings, stabbings, or shootings at large events and venues.

“Physical security isn’t just about walls and gates,” he says. “It’s about layering your defenses. A well-protected location combines technology, training, and tactical planning to help minimize vulnerabilities.”

Richmond highlights several key physical security tactics his team considers when planning event security:

  • Perimeter protection – For example, using vehicle or other hardened barriers or fencing to deter unauthorized entry.
  • Access control and screening – Such as installing metal detectors, bag checks, or canine teams for higher-risk events.
  • Surveillance and monitoring – For example, positioning cameras with real-time analytics to detect suspicious behavior.
  • Emergency response and evacuation – Such as developing lockdown procedures and well-practiced evacuation routes.
  • Staff training and drills – For instance, conducting scenario-based exercises to help ensure everyone knows their role in a crisis.

“These considerations are essential for creating layers of defense that can deter attackers and help staff respond effectively if a threat materializes,” says Richmond. “Even small enhancements can make a real difference in keeping people safe.”

Putting It All Together

From my experience and the insights of these experts, several key takeaways stand out:

  • Know your venue: Understand your location’s unique characteristics and tailor security accordingly.
  • Monitor for signs: Use social media and community input as early detection systems.
  • Assess and address: Implement a threat assessment process to help evaluate and mitigate risks.
  • Strengthen physical security: Use layered defenses to reduce vulnerabilities.
  • Empower individuals: Train staff and provide the public with clear guidance on responding to incidents.

While no strategy is foolproof, a thoughtful, risk-based approach—combined with expert insights—helps create safer environments for everyone.
