My brother was charge with Common Assault Domestic Violence - long story but they were both in the wrong but only he was charged. He is on a 12-month good behaviour bond, and will never do it again. He recently had a simple argument with his wife about their child's haircut of all things and she threatened to call the police to say he broke his conditions. He swears he never threatened her or was over the top - just stating his position which I think is his right as a father. He is very worried even a normal day difference of opinion can now be turned into a jail term if his wife feels like it. How worried should he be?
