Representative matters that have required homeland security expert witness services include school safety, emergency management and emergency preparedness, workplace violence, cyberattacks, negligent security, hazardous materials, and counterterrorism. DHS has seen its share of lawsuits, including allegations related to the public charge rule, unlawful law enforcement, asylum, and violation of the Information Quality Act, among others.

Litigation support by a homeland security expert witness could include a security assessment, an expert report, expert opinion, and courtroom testimony. Attorney clients may also utilize a homeland security or cybersecurity expert for pre-litigation consulting work.
