The self-discrimination clause of the fifth amendment is a clause that protects people from being forced to give testimony that would incriminate themselves. In a perfect world, it would only apply to people who have a legitimate threat of being incrimination if they truthful answer testimony, but there have been cases where a witness, refuse to answer quesion under the fifth amendment, essentially lying to the court, and falsely claiming that the answer would incriminate them even though it wouldn't. The law current protects people who do this from being charged with purjury, do you think this should change?
