I agree that love is far more powerful and preferable to guns and violence. But justice is also God's will, and he wants us it "done on earth as it is in heaven." If we don't want the youngsters resorting to guns and violence to get justice, then we, their elders, need to show them a better way and not stop until we've made their world far more just than it is today. We owe it to them. We owe it to our Father in heaven.
Love to you and the whole family - but especially to Tyrelle. My heart aches for him and for you all.
