A grandfather is getting tons of heat for leaving his three grandchildren behind when a fire broke out in their apartment and he fled the scene. The grandchildren, ages, 4, 5, and 8, were rescued by firemen, who also found their granddad, 66, standing totally unharmed in the lobby of the Brooklyn building. Said a neighbor: "People here want to hurt him ... They were like, 'How could you leave those kids in the house?'" Spoken like someone who's never been in a fire.
