Each of us, through the course of our lives, become embarrassed for whatever reasons; or someone plays a joke on us which makes us look silly.
We don't kill ourselves.
Do you honestly believe that the pranksters intended to cause death or serious injury? Do you honestly believe that this tragic event could have been foreseen by them?
Whilst I feel for the children, I also believe that the pranksters do not deserve to be thrown out to the wolves.
