What would happen if 10-20 DF people walked into the hall at the same time.
Fill the back two rows of the KH. The elders are told that all on the back row are DF.
After the meeting is over all 10 or 20 DF folks start socializing with JW members.
You think they would call the police, are just say what the hell....
Sometimes I do think outside of the box.LOL
