The question is - what excuse could it possibly concoct as to why it didn't comply with such a simple law?
In response to the UN scandal, I believe the Society made the excuse that 'the requirements were changed,' and implied that as soon as they found out they disassociated from NGO status. (In reality the requirements did not change.)
They may try the same tactic with regard to the WWC Act, claiming it didn't apply to them, but then it was changed.
Or perhaps they will say the law still doesn't apply to them, but "to be a 'shining example' to the world we decided to comply anyway, and doesn't this give us one more reason brothers to align ourselves with God's clean, earthly organization today!"
Regarding the toxic waste, they may say it was perfectly legal to dump at the time, therefore they are not in violation. Their responsibility to avoid 'ruining the earth,' whether legal or not, will be ignored of course.
Spin meisters never run out of something to say. And followers who refuse to investigate and think for themselves will will be happy to swallow all of it.
