If it happens to you it is a 100% result.
Just like it's a 100% result if your plane crashes. But we know that, statistically speaking, airline travel is safe and crashes are pretty rare.
So, of the million of interactions between men and unaccompanied children, how many result in some crazy, unjustified child-molester accusation? I'm guessing it's about the same as the percentage of flights that crash.
I don't believe that a handful of anecdotes, considered in isolation, are a good basis for making decisions.
