I am passionate about this because it has so deeply affected me.
Hurricane Hugo in South Carolina was a chance for individual JW's to show their love and compassion. I lived there and lost my car to a tree falling on it, and the trailer I rented fell off it's blocks. There was no "approved brothers" requirement and no "money-only" request at the time.
JW's came with chain saws and power tools and lumber and clothing and food. Some JW's from North Carolina donated an older car to me, and I drove it for years. I had a cabinet full of canned goods. And the "ear-marked" money donated to WTS was in excess because most volunteers brought their building supplies or bought them with the cash from passing the hat. So the excess- they asked any if they were out of work or otherwise lost revenue and valuables. I was given a check for approximately 2 weeks worth of work. They had to spend it on the disaster, as it was ear-marked. There was no asking victims for their insurance money.
I went to Hurricane Andrew relief and it was similar, but WTS started buying the building material and organizing the work load. Still, it seemed a good idea. But after that disaster, I could tell that things were different and they went too far. DO NOT DONATE CLOTHING AND FOOD AND CARS AND STUFF. That was too far.
ONLY APPROVED BROTHERS WILL GO IN AND HELP. I think JW's go in anyway without that process, but then they have to face the wrath of not showing love the Watchtower way.
