I agree to an extent. I would want them "rescued".
But granny assisted them in the first place. According to granny, she accompanied her daughter and the 5 kids going on a holiday to Malaysia. Pull the other one, a family packing to go on a holiday looks very different from a family planning to not come back. She knew and she did nothing about it. Now she is blubbering to the ABC that no one is helping.
Reap what you sow.
