Another one that certainly applies here is "Extraordinary claims require extraordinary proof." In this case we have no proof from the accuser. None. No proof that Bialek was in D.C. staying alone at a Hilton Hotel on the date she claims this happened. No proof that Herman Cain was in D.C. on the same day. That would be the most minimal beginning of establishing circumstantial evidence. But we don't have even that.
My new slogan:
If the dress ain’t got no stain, you MUST acquit Cain!
Cheers
You are 100% percent correct.
