The picture they show of him it looks like he's constipated. Maybe if he would have just found the aisle with the Metamucil in it and took care of his problem, he wouldn't have had to take his frustration out on a two year old.

But seriously, this man has problems. I wouldn't even strike any of my own children at the age of two for crying, let alone a strangers child. I think all of us parents know especially around the "Terrible Two" age, sometimes there's nothing you can do to keep a child from crying.
