You're being intellectually dishonest, the argument was never that he did not have "perfect memory of all his text messages," it was that in discovery he claimed he searched for and found _no_ text messages pertaining to Sandy Hook, when in fact the evidence accidentally revealed by his own counsel showed that relevant messages did exist, and were retained. A perfunctory search for the term "Sandy Hook" should have turned up those text messages, meaning he either lied about performing the search, or (more likely) lied about the search not turning up anything. Either way, abuse of discovery.
