One of the most important things you can do when listening to a person who is reporting a compliance violation or making a whistle-blower complaint is to ask them the following question, “Is there anything else you think I should know?”  This open-ended question allows the person to think about whether there is anything that they failed to tell you because they weren’t sure it was relevant.  It opens up the possibility of being told details or additional stories which will help you with the case.
