Corrections chief executive on accused mosque shooter's letter

Corrections are imposing unprecedented restrictions on any letters written by the man accused of the Christchurch mosque shootings. Not only will his letters now have to be scrutinised by intelligence experts and psychologists, but only the head of Corrections will be able to approve any letters being sent. Tighter controls are also being imposed on any other inmates with extremist views. The clampdown comes after one of the nine letters the accused gunman has written in prison ended up on a website that is popular with the far right. Corrections' chief executive Christine Stevenson spoke with us live on the programme.
