He needs an ass kicking himself for ever putting his daughter in that situation in the first place.
My 2 cents.
On the one hand, I really wish that we lived in a world where you could take your children to things like that without fearing for their safety.
On the other hand, we've had nothing but repeated evidence that you CAN'T take your kids to anything anymore without fearing for their safety.
It's pathetic.
The goon is the criminal!
Get over it!
