Honestly? I sincerely doubt you, or anyone would actually, really, for realsies, go to prison for eight years for $50M. Anyone would beg to be released after a few weeks.
That is a complete middle class mindset. Jail is cool in the hood. I've done a few months for stupid stuff when I was young and it's not that bad.
People risk 10 years for robbing bands for a couple thousand. A guaranteed $10 million would have lines around the block for volunteers in the neighborhood I grew up in.
