The document presents a dilemma regarding a physician's duty of confidentiality towards their patient, Shelby, who is wanted by the FBI for explosives-related crimes. If the physician cooperates with the FBI by disclosing Shelby's medical information, Shelby could be apprehended along with any associated criminals, improving public safety. However, doing so would breach the physician's duty of confidentiality towards their patient. Most ethical principles support maintaining confidentiality, but in this case reporting Shelby may be justified given the threat to public safety from explosives.
