I was raised by a mother who woke each morning gave me breakfast seen me off to school and when I returned each day she was there to greet me. That is the way we raised our children,if you can't or are too lazy to so then simply please don't have kids.
Look we are living in a broken society, failed marriages,single mothers, drugs, poor public schools and extremely angry children, don't misunderstand I am not making excuses there is never an excuse for this type of shooting but children today have 50 times the pressures I had growing up in the 40's-50's. We simply are failing as a society in morals, standards, greedy, knowing right from wrong.
This is not a gun problem but the extremes of our society.
