Video shows KL Rahul laughing at umpire's decision after being given out

India opener KL Rahul laughed and talked to the on-field umpire after being declared caught behind out by the third umpire following a review by Australia on Day 1 of the Perth Test. The third umpire didn't look at all the angles possible before signalling Rahul out. Rahul had suggested that the ball had hit his pad and not bat.
