I admire those who are tasked with keeping the peace, but that isn't quite the same as peacemaking. Peacekeeping is about keeping the lid on the pressure cooker. Peacemaking is about turning off the heat under it. To my mind, it's the difference between the peace of the world and the peace of Christ. And there are indeed some members of the police who are both peacekeepers and peacemakers and they are heroic.

By the way, are you sure Fr. Pfleger didn't say "sniff you out" instead of "snuff you out?" That would seem to make more sense in context.
