What is a requirement for a private investigator to operate legally?

For a private investigator to operate legally, they must be registered and licensed by the state. This requirement ensures that an individual has undergone the necessary training and background checks mandated by the state's regulations. Licensing serves as a regulatory measure to maintain professional standards, accountability, and protection for clients who seek investigative services. Each state, including Ohio, has specific laws governing the licensing of private investigators to ensure that only qualified individuals can operate in this field.

The other options may suggest beneficial qualifications or experiences but do not meet the core legal requirement necessary for the operation of a private investigator. For instance, while having a degree in criminal justice might enhance a private investigator's knowledge, it is not a legal requirement. Similarly, being an employee of a law firm or participating in an internship program may provide practical exposure but does not substitute for the legal obligation to be licensed and registered at the state level.
