I think I can arguably top the Hedgehog in terms of outrage. Grandparents reportedly planning to kill their grandchildren at the behest of their son, who is in jail awaiting trial for charges involving sexual molestation.
This is just... outrageous is probably the best word that comes to mind. If they are convicted of this crime, Old Sparky is just too good for the grandparents and the person awaiting trial. The State of Florida needs to see if the GRU would be willing to rent out a blast furnace and conveyor belt, and sell three gurneys.
In this case, the old-school approach is probably the best approach to this.
