Conservatives who claim that the ACORN, Planned Parenthood and now NPR "expose'" tapes show evidence of obvious mendacity on the part of each of those organizations are like those who jumped on the shooting of Rep. Giffords as proof that the "lock'n'load" verbiage used by conservatives was deliberately (or at least irresponsibly) inciting.

In each of these examples, people weigh more strongly that which they believe vindicates their fears/beliefs, often to the detriment of verifying veracity.
