Scottie and the Big J talk with Walter Mikac who has dedicated the last 20 years of his life to fighting violence against children.
They are reminded Walter was instrumental in lobbying for changes to gun laws after the Port Arthur massacre where his two children and wife were killed. Since then, there have been no mass shootings in Australia.
The Alannah and Madeline Foundation has worked on changing policies and working in schools to combat bullying. After 20 years, Walter will speak at his book launch in Hobart Letters of Love.
