Radio produced and broadcast by prisoners for prisoners has emerged as something of a media social movement with initiatives and developments happening in many parts of the world. Charlotte Bedford played a founding role in the establishment of the UK National Prison Radio service and her book, “Making Waves Behind Bars”, just published, presents a history of the Prison Radio Association in the UK. Currently she’s investigating ways that radio can be used - both inside and outside of prisons in South Australia - to improve the wellbeing of prisoners and better prepare them for reintegration into society.
