Final answer:
Able's impersonation of a police officer to obtain financial records is not legally acceptable. This action could result in criminal charges and make any evidence gathered inadmissible in court.
Step-by-step explanation:
No, Able's use of impersonation in this situation is not legally acceptable. Impersonating a law enforcement officer is a criminal offense in many jurisdictions, even when performed by a private citizen such as Able, a fraud examiner. The approach Able has taken could lead to legal action against him and his employer, XYZ company, for engaging in illegal activities such as misrepresentation and obstruction of justice. Furthermore, any evidence obtained through these means could potentially be deemed inadmissible in court. It is essential that investigations are carried out within the bounds of the law to ensure that they are both ethical and legally valid.
