Mr. K: "I suppose the pressure cooker bombs they threw at the police while trying to escape (using the same pressure cooker as the original bombs) and all the bomb-making supplies they found mean nothing to these people."

Change.Org: "The explosions were car backfires, and the supplies were planted."
