In 2008 a grainy CCTV image appeared in south London newspapers of a young man robbing a cash and carry. Sarah O'Connell tells the story behind the photo.
Everyone has seen similar pictures - of a surly young man who has committed a serious criminal offence. Yet as a society we have not been very successful at stopping them from doing so.
Sarah takes that CCTV picture, and one of Aaron as a baby, and explores what went wrong with Aaron's life in the gap between the two pictures which resulted in him committing a serious, violent criminal offence before he had yet turned 18.
In the programme Aaron himself discusses his life with candour - from his family background to his motivation for committing criminal offences. Sarah also speaks to members of his family, teachers and mentors to give a rich picture of how a life can fall apart - and perhaps what we might do better in the future.
