That's so sad. I can't ever remember, in my 61 years on this planet, ever seeing something like this. I do remember when a kid came into a Burger King where we were eating and demanded money from the register. I chased him out of the restaurant and down the parking lot. I held him down until the cops showed up. I was a hero to my boys for that day. Then there was one too many dad jokes and I was just "dad" again.
But the need to destroy just for the sake of destroying is beyond me.
