Just like my step-son.
The story changes as new facts come to light.
As Robert Heinlein has said:
"The first way to lie artistically is to tell the truth — but not all of it."
He also said:
"Reason is poor propaganda when opposed by the yammering, unceasing lies of shrewd and evil and self-serving men."
And
"You can sway a thousand men by appealing to their prejudices quicker than you can convince one man by logic."

It's not about who's right, it's about what's right.
