I agree with Clyde when he says JDS maybe don't even remember grabbing the fence. He was so in a walking coma state I believe instincts kicked over and he just grabbed the fence several times. Although we all know it's a plain foul, there's a BIG gap between the scenario in which that happened and to label the guy a straight "cheater".
