According to Carter, LaBeouf replied, "Oh yea? Or what? What are you going to do about it?"

Carter says he then tried to calm LaBeouf down and prevent him from re-entering the bar, causing the actor to scream at him, "Well what if I grabbed my knife on you?"

LaBeouf never flashed a weapon, Carter says, and instead walked away from the bar. But Carter says LaBeouf walked in front of a window a few minutes later and "made a throat-slashing gesture" at him.
