Let me pose a hypothetical situation. A woman is drawing Social Security disability benefits. She posts on Facebook: "Having a great time visiting Disneyworld with my grandchildren." Along with this she posts a photo taken of her and her grandchildren at Disneyworld. In the photo, she's smiling.
Does this hypothetical situation bother you? If so, why? Do you think the information given should trigger some sort of investigation? If so, what sort of investigation and why? Do you feel that you need more information in order to answer these questions? If so, why?
