I think this is one of the worst things a con-artist can pull.  Offering evidence on a public stage that can be so easily trumped as doctored and contaminated with her own bias.  I mean, look at us foaming about it.  I offer a slightly different take: This is what a cult-leader would do.  Offer a doctored reality to his acolytes to help confirm the bias they already hold and cement their loyalty even more.
