In the Rio 2016 Olympic volleyball final match's third set, a Brazilian player was spiking very close to the net. After his spike, his arm followed down, contacting the arm of the Italian blocking player, and making their hand touch the tape (the top of the net).
Since the ball was in play, the referee decided that this was a point for Brazil. But this touch of the net happened at about the same time as the ball hit the ground.
According to the rules, whose fault was this? Was it still the Italian player's fault because he touched the net, or was this a bad call by the referee, and should have been a point for Italy?
