I think it would be an obligation of this society to sentence this wild animal to hard labor and hard discipline for a few years and don't allow the typical story of mommy being a drunk and daddy not caring as an excuse to do evil. She knows what she did was wrong.
What does the military do to establish hard discipline? They break you down and build you back up again. When it comes to violent offenders we tend to skip the break down part and that is why these animals are repeat offenders who will never break the cycle of hate, violence, drugs, sex and deviancy.
Part of the success of a break down is a sense of accomplishment when you are rebuilt. Feeling sorry for people doesn't help anyone.
The story states that someone recorded this on a cellphone.
I am convinced the real reason cellphones are prohibited at school is because incidents like these can and will be recorded, exposing the true nature of these institutions and the people in charge of them.
my wife has said that we should bring back mandatory military service.
