translation according to youtube:

After the security guard swatted it to the ground, Kasparov says, "I think we have to be thankful for the opposition's demonstration of the level of discourse we need to anticipate. Also, apparently most of their arguments are located beneath the belt." Someone in the audience shouts, "Finally the political power shows its face!" Kasparov quickly replies, "Well, if that's its face..." to laughter from the audience.
