Chase Utley's "Dirty Slide"

Many people have been going back and forth about Chase Utley's slide that broke Ruben Tejeda's leg. And in my opinion on the topic is that the slide was dirty. Before everyone starts telling me I am full of it let's look at the rules according to the MLB's official rules 7.09 (f) "If, in the judgment of the umpire, a batter-runner willfully and deliberately interferes with a batted ball or a fielder in the act of fielding a batted ball, with the obvious intent to break up a double play, the ball is dead; the umpire shall call the batter-runner out for interference and shall also call out the runner who had advanced closest to the home plate regardless where the double play might have been possible. In no event shall bases be run because of such interference." In shorter terms this means every player in that play should be automatically out and the inning is retired. The rules clearly state that what he did was illegal.
