Just another instance of putting up a fence of law ineffective law enforcement after the raging bull of self gratification escapes from the barn of discipline. If children were disciplined at home before going out in the world, expecting that they will be able to do whatever they want, and talk their way out of it, there would be a lot less of these kinds of disasters. I am not worried about the guns. People use clubs and knives in lieu of guns and lately explosives to rage against a society they blame for messing up their lives. The number of deaths are not the point. The point is that these attacks are occurring more frequently the more people allow children to run their own lives.
The bible is only concerned that children not lose their lives due to discipline, not that they are mentally damaged by it. Indiscriminate discipline is not the Christian way, so I am not condoning parents beating a child, but a switch to the bottom drives out evil, as Solomon said.
Proverbs 12:1 Whoever loves discipline loves knowledge, but whoever hates correction is stupid.
Proverbs 22:15 Folly is bound up in the heart of a child, but the rod of discipline will drive it far away.
Proverbs 23:13-14 13 Do not withhold discipline from a child; if you punish them with the rod, they will not die.
14 Punish them with the rod and save them from death. [From the New International Version (NIV) of the bible.]
