Someone should have been there with that child when he came home from school. Yes, I know the government has cut back, but where there is a will, there is a way. I'm speaking as a mother that raised three children almost entirely on my own. I traded babysitting with someone that had a different schedule than mine and all sorts of things. I really feel for all the people involved, even the ones you left out.
Someone has to pay for that life.
If a child decides to take an adult weapon and commits an adult act, then he should be tried as an adult for his negligent actions. Give us all a break from this mindset and allow justice to prevail. If that had been your child gunned down in the street, you would be singing a different tune. I just cannot believe that the government failed this child. It really hurts me to see this child like this.
