Verification attack (logic)

A verification attack is a logical technique where you ask your target to verify their views on a particular topic, such that later on they are unable to backtrack or change their views when lying.

Usage
Usually, a verification attack is as simple as asking the individual in question as to whether or not they still hold their original view, or whether or not they are still convinced of their lie.

In some cases, the mere act of asking if they are sure of their lie may make them falter fearing you know more than you are letting on.

Preferrably the attack should be performed in the public domain or on some means of recordable media such that they are unable to change their story without other people knowing about it or without proof exposing their lies.
