Inside of the Customs and Border Protection Standards of Conduct, it clearly states that 'every CBP employee is required to report allegations of misconduct immediately.' There are a variety of approaches to reporting misconduct, including by phone, email, or writing to Internal Affairs or Homeland Security. Take the time to review the Standards of Conduct so that you are fully prepared to discuss how you would correctly handle an issue of misconduct.
If you have a specific example of a time when you faced this situation, provide your story example using the STAR method (Situation, Task, Action, Result). Using this framework will help you to provide a well-organized and engaging response. Otherwise, offer a hypothetical example outlining the fact that you would follow CBP protocol to the letter.
