It casts a shadow over our society when such appalling crimes can be committed by young people.
There is a section of our society where standards, responsibility, self discipline, care for others is either lost or blurred.
Children are shaped by how they are brought up by their parents, nurtured and taught to lead an active and responsible place in society.
When that does not happen why are we surprised when sink estates become ghettos and places of fear.
While we all ruminate on the hows and the whys four young people now have shattered lives.
Professional people such as care workers, police and social services have once again failed.
As for the parents, if you can't raise your kids then should you be allowed to keep them.
