This is a tough one for me.

This guy took millions of dollars in people's private investment. Found the treasure, hid the treasure, and then refused to comply with a court order to make the investors whole.

What should the punishment for this be?

I'm saying that a judge having the power to do that to anyone is wrong. I'm not talking about this particular case.

The power of a judge should never exceed scolding and recrimination.

they invested 12 million and he provided 50 million no?
