I have a five year old son, and let me inform you that being squeezed against hard seats like that can HURT a child.
His reaction afterward was one of ambivalence. That's what broke the final straw in my eyes. He could see the kid sad and hurt, but he taunted the crowd insteadand acted proud.
He was a Jerk!
He was an Asswipe!
and he deserved every insult thown at him!
But I am happy he apologized. That will redeem him.
