Interviewing Tips - Judgment Scenarios
Answer To Judgment Scenario #2
There is nothing wrong with asking to look at the suspected counterfeit bill. Unless you are a Secret Service agent, you should not take possession of the bill. There is no sense in getting involved in the chain of custody. If the bill appears to be phony, tell the cashier to report it to the Secret Service. You may also want to notify them.
The key to this question is to notify the proper authorities. Even though you are a police officer, it may not be your responsibility or jurisdiction to investigate this type of crime.
