Which of these must not be displayed by a private investigator while executing an arrest warrant?

During the execution of an arrest warrant, private investigators must adhere to certain regulations regarding identification to ensure they do not mislead individuals about their authority. A badge implying federal authority does not belong to a private investigator, as they operate under state law and do not possess federal jurisdiction. Displaying such identification could cause confusion or misinterpretation among the public or law enforcement regarding the investigator's role and authority.

In contrast, business identification from their agency, identification indicating they represent a bail bond surety, and possibly a uniform compliant with local laws are appropriate forms of identification that help clarify the investigator's role and responsibilities during the execution of the warrant. This ensures transparency and maintains the legal integrity of their actions while carrying out their duties. The use of an inappropriate badge could not only mislead those involved but may also lead to legal repercussions for the investigator.
