From NRA-ILA:

When law enforcement came to Dunstan’s farm to investigate the incident, police confiscated the rifle he used to defend his family, along with two others. Upset, Dunstan told the Herald Sun, “What are you supposed to do if someone was breaking into your house… I don’t know what, as a law-abiding citizen of Australia, we’re supposed to do?” Dunston went on to say, “The police have handled this the wrong way (and) I can’t get an answer out of them.”
