Uchiha-Itachi is wrong, mut@t@ is right. gai's tactic only nullifies the genjutsu techniques a sharingan user exercise. a sharingan user does not need to make eye contact to predict movements and jutsu. and theres a big difference between itachi and kakashi's sharingan, the biggest of which is the manga sharingan or whatever, but what about the black flames he used in 85? plus itachi has an uchiha's body, so he can use the sharingan longer and more precise than kakashi.
