She would still be able to hurt people like her husband and her children - assuming she is manipulating them to help mitigate a criminal sentence. More generally, she could manipulate and scam anyone she is exposed to. Putting her in prison would reduce the risk of that harm. There is also deterrence to think about. In some sense, we could ban Holmes from being an executive in any company or from handling client funds or something and probably she would never be a problem for society again. But, if other, would be fraudulent CEOs knew that defeat meant a slap on the wrist, they would be encouraged to take risks and bend the rules. Generally, I am in favor of prison reform - but I think easing the sentences of the rich and powerful is a poor place to start.
