This door and that twig story were points of confusion and conjecture not only for the first jury but for many people. During the first trial they did not have enough photos. They are impeaching every thing JY said from his 1st trial, now that his "story" is on the record.
To me they can't emphasize these points enough! As we saw yesterday, unless facts are pounded into many people's heads several times, they simply don't remember and can't seem to retain more than what they heard 30 min before, and even then...the info gets missed, misconstrued, etc.
