Well... this is justice. Sadly, we don't get to see justice very often. This is life in prison, correct? I know he hasn't been sentenced but all counts is easily several life sentences at the federal level. When do the parents go on trial? I can't see how they make it out of this without at least having all their ill-begotten assets stripped.
Have all of the people scammed been brought whole? That would be justice. Someone sitting in jail isn't justice. It is punishment for his actions. I've never understood how someone being incarcerated has become considered justice.
Can you ever make them whole? Even if you pay them back all their money, there is the period of time without, the fear and pain from losing it, and similar that cannot be undone. For other crimes, there is often a victim whose state can never be fully reverted. If this is our view of justice, then justice becomes an impossible thing which can never be achieved. Does such a stance risk people eventually no longer chasing what can never be acquired?
