In the intricate world of premises liability cases, the expertise of a security expert witness is invaluable. Whether it’s negligence, foreseeability, use of force or related, these  cases often involve determining whether the threat was known and if adequate controls were in place to minimize the potential for a threat occurrence. A premises security expert should bring unbiased insight to support the understanding of the trier of fact. This role requires a deep understanding of security management, security technology, crime,foreseeability, and best practices in safety protocols.

What Does a Security Expert Witness Do?

A security expert witness provides expert analysis in cases involving security negligence and premises liability. Their job goes beyond reviewing security footage or policies—they evaluate every element of the incident to determine if lapses in security contributed to the harm. These professionals often have backgrounds in security management, crime prevention, and forensic analysis, making them uniquely equipped to address complex cases.

Key Contributions of a Security Expert Witness

1. Analyzing Security Measures

At the core of every premises liability case is the question: Were reasonable security measures in place? Ahrens Security can evaluate physical, operational, and technological controls, such as:

• Surveillance systems: Were cameras operational and positioned effectively?

• Access control: Was entry to the premises adequately restricted?

• Keying control: Was a keying system in place was it controlled?

• Barriers: Were barriers in good repair, were the sufficient for foreseeable threats

• Lighting: Was poor lighting a contributing factor?

• Policies/Procedures: Were policies and procedures in place, did they support training?

Through exhaustive reviews, Ahrens Security assess these measures against industry standards and legal requirements and can determine and show the effectiveness or lack of security..

2. Crime Foreseeability and Analysis

Foreseeability is critical in premises liability cases. A security expert reviews crime demographic data, historical incident reports, and local crime statistics to determine if the property owner should have anticipated criminal risks.

For example, if prior incidents of theft or violence occurred, was the owner proactive in addressing these threats? Sean Ahrens specializes in visually demonstrating foreseeability using data-driven analysis and graphical evidence, simplifying complex data for attorneys, jurors, and judges.

3. Site Condition Evaluations

A thorough evaluation of the property is necessary, and can confirm vulnerabilities that may have contributed to the incident. This includes:

• Documenting existing conditions, such as damaged locks, broken cameras, or unlit areas.

• Identifying design flaws through principles like Crime Prevention Through Environmental Design (CPTED).

4. Providing Expert Testimony

A security expert witness offers unbiased testimony that can strengthen a case. Whether for depositions or trial, their insights clarify whether the property owner’s actions—or inaction—contributed to the incident. Sean A. Ahrens is known for his ability to make even the most complicated data accessible through clear, visual presentations, ensuring the trier of fact fully understand the complexities of the case.

Common Scenarios Requiring Security Expertise

Security negligence spans across industries and environments. Some of the most common cases include:

• Workplace violence: Examining preparedness for active shooter situations or assaults.

• Retail and hospitality: Assessing security failures in stores, hotels, bars, and restaurants.

• Apartment buildings and parking garages: Evaluating lighting, access control, and surveillance systems.

• Negligent hiring and training: Reviewing hiring practices and training for security personnel.

• Parking lot/garage: Determining whether security measures in parking garages were adequate to prevent harm.

• Entertainment/Bar: Was training in place to prevent the occurence. Was there a weapons screening program in place? Were staff educated about drugging/sexual assault, over serving?
