The father of Southport killer Axel Rudakubana stopped his son from returning to his former school a week before he stabbed three young girls to death in July last year at a Taylor Swift dance class. James wonders how scared Rudakubana's father was at what his son was capable of and asks what parents with potentially violent children can do to prevent the worst.
