What Makes Open Spaces Different: A Look at Waterfront and Park Security

For the municipalities, property managers, and private operators who oversee these environments, a useful starting point is not a checklist but an honest look at how the physical and social character of a space shapes the risks it may carry, and whether current practices still align with those conditions.

Seasonal Crime Patterns and Environmental Risk: An Operational Perspective

Security professionals and property managers who work across commercial, hospitality, and residential environments often observe a familiar rhythm in how certain types of incidents tend to cluster around particular times of year. Summer months, in many regions, bring with them a combination of social, environmental, and behavioral conditions that have historically corresponded with increases in property crime, public disturbances, and related security concerns. Understanding these patterns through the lens of foreseeability offers a useful foundation for those responsible for managing risk across a range of property types and right sizing security deployments.

Seasonal Crime Spikes & Environmental Risk Factors

As the temperature rises, so do the risks of property crimes. In many warm-climate regions, seasonal crime spikes are a recurring trend during the summer months, with increases in incidents like theft, vandalism, and burglary. Understanding the environmental risk factors that contribute to these seasonal upticks is key for both property owners and business managers to develop effective prevention strategies.

Security Considerations in Family Entertainment and Dining Venues: An Operational Perspective

Family entertainment centers that combine dining, arcade gaming, and large-scale attractions occupy a distinctive space in the hospitality and entertainment landscape. These venues are designed around the idea that volume drives viability. The more guests who walk through the door, the more the business model works. That orientation toward high occupancy and broad accessibility creates an environment that is genuinely welcoming by design, and it also introduces a set of security and operational considerations that are worth examining thoughtfully.

Access Control and Physical Security in Commercial Properties: Operational Considerations and Evolving Practices

Commercial properties encompass a wide spectrum of environments, from office towers and mixed-use developments to parking structures and healthcare campuses. Across these settings, access control remains one of the more foundational elements of a broader physical security program. How it is designed, maintained, and integrated with other security functions tends to shape both day-to-day operations and how a property responds when unexpected situations arise.

Building/Security Group 2026 Live Web Panel Discussions

I was pleased to participate in the Building/Security Group 2026 Live Web Panel Discussion series, hosted by Security Info Watch, across three sessions this past May.

The series covered topics that I find particularly relevant to the work we do every day in physical security and risk management.

Crime Prevention Through Environmental Design Misapplications in Suburban & Commercial Areas

Crime Prevention Through Environmental Design (CPTED) is often referenced as a component of security planning, particularly in urban environments. By considering how physical spaces are arranged, CPTED focuses on factors such as lighting, layout, and visibility to influence how areas are used and influence those that may contemplate illegitimate, nuisance or criminal activities. In suburban and commercial settings, however, application of these principles may vary, especially where design priorities and functional considerations intersect.

Why Police Reports sometime don’t Reflect Actual Risk on a Property

Police reports are commonly used when evaluating safety conditions at a property. They can inform liability discussions, insurance considerations, and legal strategies. However, they represent one source of information among many and may not capture the full range of activity occurring in and around a location.

Parking Structures: Recurring Vulnerabilities

Surveillance is one factor often reviewed when evaluating parking structure environments. Some garages operate with systems that were installed many years ago or that have not been updated. In those situations, monitoring conditions may vary across different areas of the structure. Claims involving parking facilities sometimes reference questions related to surveillance coverage, equipment condition, or visibility.

Workplace Violence Trends Affecting Multiple Industries

Workplace violence is a topic that has received increasing attention across many industries, including manufacturing, corporate offices, retail settings, and hospitality environments. Incidents involving aggressive behavior, threats, or physical confrontations occasionally arise in professional settings, leading organizations to examine how workplace conditions, communication practices, and security procedures influence employee safety.

The Weaknesses of Aging Buildings Across the U.S.

As many buildings across the United States continue to age, maintaining and upgrading security systems has become increasingly important. Older properties, especially those constructed before modern security technologies became standard, often face challenges that leave them more vulnerable to crime.

While these buildings may have strong structures and long histories, their security infrastructure frequently has not kept pace with today’s risks.

Security Controls in Multi-Family Housing: What Works, What Fails, and What Truly Improves Safety

Security in multi-family housing is no longer viewed as a luxury. It is a core part of tenant safety, property performance, and community trust. As residential communities grow and criminal behavior becomes more sophisticated, property owners and managers must think carefully about how security is designed, maintained, and supported day to day.

Through years of evaluating properties and advising clients, I have seen how small gaps in security can quickly turn into major vulnerabilities. I have also seen how thoughtful, layered security measures can significantly improve safety when they are consistently applied.

How “Reasonable Security” Varies by Region and Why It Matters in Lawsuits

When it comes to premise liability and negligent security cases, the concept of reasonable security is often central to the discussion. What is considered "reasonable" security can differ greatly depending on the region, local crime patterns, building types, and even cultural expectations. Understanding these regional variations is critical for the trier of fact, as it helps define a standard of care.

Regional Crime Patterns & Foreseeability in Premise Liability

In premise liability litigation, foreseeability—whether a property owner should have anticipated a risk—is central to understanding foreseeability. Increasingly, attorneys and expert witnesses rely on crime pattern analysis and public crime datasets to demonstrate whether the risk of certain crimes was predictable based on trending.

Inside Bar & Entertainment Venue Incidents: How Environmental & Operational Failures Create Negligent Security Exposure

Bars, nightclubs, and entertainment venues operate within fast-paced, high-energy settings where alcohol consumption, dense crowds, and constant movement significantly elevate risk. These environments routinely experience predictable forms of disorder, including altercations, falls, theft, medical emergencies, and assaults. Because these conditions are inherent to nightlife operations, the central legal question in negligent security cases is whether the venue took reasonable steps to address foreseeable hazards.

Security Challenges in Bars & Nightlife Venues: Managing Risk in High-Density Environments

Bars, nightclubs, and entertainment venues operate within one of the most dynamic and unpredictable security environments. Unlike retail or office spaces, nightlife settings combine high occupancy, low lighting, alcohol consumption, and elevated social interaction, which together increase the likelihood of incidents ranging from fights and assaults to theft, disorderly conduct, and medical emergencies.

Entertainment Venue Security: Avoiding Common Pitfalls

Entertainment venues concentrate people, emotion, alcohol, cash, and social media into tight spaces and at predictable times. This makes them attractive targets for opportunistic crime, interpersonal conflict, and disruptive crowd dynamics. From a negligent security perspective, jurors expect operators to anticipate these realities. The difference between a near miss and a catastrophic claim often comes down to fundamentals: controlled ingress, clear egress, trained staff, and good operational security protocols.
This blog summarizes common pitfalls I see in entertainment venues and litigation, along with practical, defensible controls that raise safety and reduce exposure.

The Impact of Access Control Innovations on Premise Security

Access control is no longer just a collection of door hardware and badges; it is the operating system that governs how people, deliveries, and services move through a facility. For property owners and litigation teams, that shift matters. When a claim involves unauthorized access—tailgating, a propped door, a compromised credential—the court’s scrutiny increasingly centers on whether the access control program was reasonable for the risk profile, well‑maintained, and updated in line with available technology. In other words, innovation doesn’t just add convenience; it can influence the standard of care.
This article summarizes the practical impact of modern access control—especially, magnetic locks—on premises security. It also outlines how an expert witness evaluates systems for foreseeability, adequacy, and program maturity in Chicago and throughout nearby states such as Indiana, Wisconsin, Michigan, and Ohio.

Lighting and Safety: How Poor Maintenance Increases Liability

Lighting is one of the most critical yet overlooked components of property safety. In premises liability cases, inadequate or poorly maintained lighting is a frequent factor in determining whether a property owner or manager met their duty of care. From parking lots and stairwells to entryways and hallways, lighting design and maintenance play a key role in deterring crime, reducing accidents, and demonstrating proactive security practices.
This article explores the legal and safety implications of lighting failures, the role of lighting expert witnesses, and why preventative maintenance is a necessary investment in liability reduction.

Threat, Vulnerability, and Risk Assessment

Minimizing liability begins with three concepts: threat, vulnerability, and risk assessment (TVRA). These terms are foundational to the security profession, yet they are also critical tools in litigation and to prove or disprove negligence.
When properly applied, TVRA assessments transform complex security failures into a clear narrative. They establish foreseeability, quantify negligence, and provide the evidence needed to persuade the trier of fact. This article explores the role of TVRA in litigation, security consulting, and proactive property management.

The Changing Face of Parking Management: How Automation and Design Choices Shape Liability Risks

Parking facilities are evolving rapidly. Across Illinois and the Midwest, operators are trading cashiers for kiosks, attendants for cameras, and round-the-clock lighting for energy-efficient motion sensors. These changes promise lower costs and smoother operations — but they also bring new questions about safety and liability.
From shopping centers and airports to high-rise residential towers, parking garages and lots are transitional spaces where safety is often taken for granted. When a crime or accident occurs, plaintiffs increasingly argue that shifts in technology or staffing created foreseeable risks. Understanding how these changes impact liability exposure is essential for owners, operators, and property managers.

The Evolution of Access Control: From Keycards to Biometric Technology

Access control systems have undergone a significant transformation over the past few decades, driven by technological innovation and an evolving understanding of security threats. From the simplicity of lock-and-key mechanisms to the sophistication of biometric authentication, this progression reflects a broader shift toward more intelligent, adaptive, and risk-based security practices.
This article explores the evolution of access control, tracing its path from traditional keycards to today’s advanced biometric systems—and what that means for security professionals, facility operators, and risk assessors.

Understanding the why behind theft and vandalism is just as critical as preventing it. For property owners, attorneys, and security professionals alike, exploring the psychological drivers behind these crimes reveals more than just motives—it uncovers vulnerabilities in security programs that may otherwise go unnoticed.

Hotel Security: Reducing Vulnerabilities in Hospitality

In today’s hospitality landscape, security is no longer a behind-the-scenes consideration—it’s a core component of guest satisfaction, brand reputation, and operational resilience. Hotels, especially those in urban centers like Chicago, Indianapolis, and St. Louis, are high-traffic, open-access environments where safety must coexist with comfort.
Whether it’s a boutique property in Milwaukee, a full-service hotel near convention centers in Des Moines, or a resort outside a major metro area, hospitality operations face a complex array of security challenges that demand thoughtful planning and continuous evaluation.

High-Rise Multi-Family Security Challenges: Protecting Tenants and Assets

High-rise multi-family properties have become fixtures in the urban housing landscape, particularly in dense metropolitan areas such as Chicago, Milwaukee, Indianapolis, St. Louis, and Des Moines. These buildings offer scale and efficiency but also introduce complex and often underappreciated security concerns. As cities expand upward, building owners a are increasingly tasked with demonstrating that their security programs can anticipate, prevent, and defend against known risks.
With nearly three decades of experience in physical and operational security across a wide range of property types, I’ve found that high-rise residential buildings—particularly those with mixed-use footprints or legacy construction—require a different level of planning, precision, and accountability than their low-rise or single-family counterparts.
