A gate has never stopped a criminal from breaking in before, so it's naive to think living in such a place will make any difference in your safety. That's the naive thinking the world exhibits. Rather silly to invest in a barrier that's not going to solve crime."
Where I live almost all Kingdom Halls are "gated," having a fence all around the building. Someone has to arrive early to unlock the gate to let cars into the parking lot.
I suppose it's for a combination of reasons - to stop break-ins and to keep people away from the parking lot during non-meeting hours (skate boarders for example) where injury could cause liability issues.
"No matter where you live, Jehovah will look out for you."
If JWs really believe that, then why are KHs gated? Is this another double standard of JWs?
