BOC,
One of these pranks is going to result in a physical attack or a geriatric Dub dying of a heart attack during the event. Then the dumbass pranksters will be sued. These are the types of things that inevitably occur. About 4 months ago there was another one of these videos posted, except the pranksters entered the KH before the meeting began with video cams in hand, creating a commotion and marching around the hall. I've worked with church groups developing active shooter and other security related plans and programs. Some of them have such plans, including armed deacons. It doesn't take much to imagine one of those deacons opening fire if such an event occurred in their church.
The Dubs may be pacifists, but sooner or later someone is going to get hurt and someone is going to get sued and potentially incarcerated. Welcome to the real world he said to me, condescendingly.
