The reason they haven't caught anybody is that Satan and his demons are behind it. And can't be seen.
I'm surprised they're not playing it up as wordly persecution.
Actually, some of the stuff sounds funny. Glue in the locks? Can't even get in the hall to start at meeting. That's kind of funny to me. Seems like it'd be a project to fix and you'd have to cancel meeting or make people wait in the parking lot until it's fixed and have an abbreviated one.
Pranks are one thing, and if it's the KH, I don't feel as bad about it. But attacks on people's personal property and some of those were old ladies? Why not the elders who DFed him? Unless the old ladies were the ones behind getting him DFed. ie., reporting him. Maybe stalking him to see if he did anything wrong and then telling the elders. The guy's being a real a-hole.
It's obviously a JW if they know which houses to hit. Unless they're following cars home after meetings.
When I was a JW and probably in my late teens, I knew a guy in another congregation who "Easter egged" one of his elder's houses. That elder was kind of a jerk. Big attitude, owned his own cleaning business, made a DFed guy work meeting nights so he couldn't be re-instated - at least until his girlfriend he got in trouble with got married. The guy was an a-hole. And the guy who egged him was a JW in good standing.
So this guy colored eggs in pastel colors and decorated them. ie. Easter eggs. And the night before Easter egged this elder's house. Also leaving some colored eggs intact around the yard and under the bushes so it'd look like what you'd have for an Easter egg hunt. I thought it was hilarious. Not only did his house get egged, but the shame of appearing to the neighbors as if you celebrate a worldly holiday. Oh my!
His neice, who went to our hall and also knew about this & who did it (and liked the prank too), said they called the police and reported it as somebody from his kid's high school and even had an idea of who. Their reasoning? That it couldn't be a JW because they're Easter eggs and JWs don't celebrate Easter.
