Luke Schwartz is a little bit heated after losing that massive pot to Ian Frazer and made the comment, "It's too retarded." about the stuff that's been happening in the tournament. One of the people on the rail who is Giovanni Safina's translator and friend told Schwartz to "shut up" becaue he thought Schwartz had called Safina retarded, when he was really only commenting on the situation. Schwartz took offense to the person telling him to shut up and they began to argue.
Schwartz may trash talk his opponents and needle them about their play, but he didn't go as far as calling Safina retarded, it was just mistakenly heard. After the tournament director stepped in to clear up the situation, things got back to normal, or at least somewhat normal.
