Lindsey Stone — the Plymouth woman taking an online beating for posting a photo of herself flipping the bird at Arlington National Cemetery on Facebook — has lost her job. “Lindsey resigned and we accepted her resignation,” LIFE Inc. CEO Diane Enochs told the Herald tonight. LIFE Inc. of Hyannis — a Cape Cod nonprofit that helps adults with special needs — announced tonight that Stone, along with the woman who snapped the offending photo, are not working there. Ironically, the formal announcement was made on Facebook.
