A private investigator is primarily distinguished by their role in conducting investigations for others. This focus on investigation means they typically gather information, conduct surveillance, and analyze data to help clients with various matters, such as legal issues, personal inquiries, or criminal cases. Their work often requires them to have specialized skills in analysis, research, and sometimes interviewing, which is different from the primary duties of a security guard.

On the other hand, a security guard's main responsibilities revolve around protecting property and maintaining safety. Their focus is on prevention and control, rather than investigation. While both roles can involve elements of observation and reporting, the context and objectives of their work are different. The implication that they have the same role and responsibilities is incorrect, as their core functions are distinct within the realm of safety and security services.

Teaching self-defense classes, while it may be a skill that some security guards possess, does not define their role; rather, it's an auxiliary service that might be offered. Thus, the emphasis on investigation clearly sets private investigators apart from the more protection-oriented duties of security guards.
