Here is the testimony of the ACLU for this trial, if you're curious about it. I watched it live and was beside myself. There are a lot more shenanigans than listed in the article. It's important to listen to the actual words spoken and changes in voice, see the facial expressions, watch the dancing around the questions, hear the contradictions.
Just look at the 'good faith' allowances granted when government officials violate the legal system's own laws and requirements. Not only is it ineffective if someone is good at lying, it just voids it's own laws and requirements if the liar is a government official because 'good faith'.
You can impeach someone and/or offer up other witnesses to chip away at a liar's credibility. "Good enough" doesn't come close to describing the level of deception necessary to render our entire legal system completely ineffective.
