I don't know if they would stop the meeting should you pull a gun and blow your brains out. They didn't stop the meeting at our hall when a motorcyclist was hurled up into the yard after a crash. He was unconscious and the EMTs had to call for a helicopter to transport him to the hospital.
They didn't stop the meeting when an old man had a seizure and tipped over in his chair.
They didn't stop the meeting when an old sister collapsed in agony. They only asked the ambulance people to take her into the foyer so as not to disrupt the meeting.
