Should the age of criminality be raised?
Maggie Atkinson said the killers of James Bulger should have undergone "programmes" to help turn their lives around, rather than being prosecuted.
Most criminals under 12 did not fully understand their actions, she said.
She told the Times civilised society should recognise that children who commit offences needed to be treated differently from adult criminals.
Do you agree with the children's commissioner? Should young criminals be treated differently to adult offenders? Is the age of 10 too young to be aware of your actions? What age do you think children become responsible for their own actions?
