GREG O'CONNOR (Labour—Ōhāriu): Thank you, Mr Speaker. Listening to the debate today, there is one thing that everyone agrees with, even though they haven't said it, and that is about behavioural change. Now, criminals will always want firearms. From time immemorial, whether it was knives, whether it was clubs, if you were on that side of society, you always wanted to back up your position with as strong a piece of machinery, firearm—any weapon—that you could. Criminals will do that. So, to make any meaningful change, we've got to change the behaviour of criminals.
