Check the Facts
Remember to follow up and vet the stories. You want to make sure - before you use the story publicly or share it with the media - that it will withstand scrutiny. Certainly the storyteller should not be made to feel uncomfortable or defensive. It is often a good idea to have another member of your organization contact her or him just to check that the person collecting the story took accurate notes, or to confirm any details left out of the recording or video. It is also a good idea to do some independent research (like 'Googling' the person) to see if any information or details are inaccurate.
To make the person more comfortable when you vet her/his story, prepare her/him that it will have to stand up to scrutiny by the media and the public, and you want to be certain she/he is ready and able to answer those kinds of questions. Then ask questions about any details that may raise red flags. If you aren't satisfied with the answers and, therefore, uncomfortable sharing the story, thank the person for her/his time and make sure the database notes your concerns. Also, take note if the person has any tendencies to direct frustration, specifically at groups such as minorities, immigrants or welfare recipients. After explaining that information could become part of a public story, your final question can be, "Would you have anything about this story or in your background that would be a problem if a reporter ask you a question about it?"
You could still use her/his story in a written format, you will likely not want this person speaking to the media or in public settings.
If you aren't satisfied with the answers to some of the tougher questions, or have any concerns about the person representing your organization make sure your concerns are noted in your database.
