Matt. 5:21-22 "You have heard that it was said to those of ancient times, 'You shall not murder'; and 'whoever murders shall be liable to judgment.' But I say to you that if you are angry with a brother or sister, you will be liable to judgment; and if you insult a brother or sister you will be liable to the council; and if you say, 'You fool,' you will be liable to the hell of fire."
Those who did not see something like the violent events of yesterday coming need to step out of their bubbles and look around.
