LAST year Glen Walters beat Gregory Lansdowne to death in a Parramatta squat because he couldn't repay a $20 debt. Both men were mentally ill, unemployed and homeless. According to the police report, Walters said he "was owed money, was drunk, angry and had wanted to teach the deceased a lesson. He knew when he walked in the back door, when he grabbed the pipe out of the backyard, what he was going to do. He knew he was going to hit him with the pipe but didn't know he wasn't going to be able to stop himself." Walters pleaded guilty, and in May this year I sat through the sentencing hearing in the Supreme Court. I was keen to see justice in action in NSW. It was the week when Andrew Humpherson, the state Opposition spokesman on justice, criticised the Government in relation to two men involved in the murder of police officers.
