Desiderata, the whole point is that the only thing we can be quite sure of is that a little girl died and her brother might have done so, too, while in the care of their father and a woman who was not their mother. Most of the rest might or might not be true. I find the rush to assume the worst repugnant and those who rush to judge equally distasteful. If that's snobbery, rarefied or otherwise, I can live with that.
I am not assuming that everything printed in the newspaper is untrue. I'm just not happy to accept it uncritically.
Your argument is no more nor less than "There's no smoke without fire". Are you really trying to put that forward as a rational, considered view?
