We don't really have a profile in that we don't have a lot of statistics because we don't have the cases before us, except for the ones that go violent. We don't know all the cases that don't ever get litigated. We don't have all that evidence.
If you look at the patterns of who dies, it is overwhelmingly white privileged men who kill their partners, and it is overwhelmingly those same men who then might engage in mass violence. They practise on the women in their lives first.
