Anything less than the harshest possible punishment is being lenient.

This isn't a case where a man is desperate for money or undereducated or is in a fit of rage or has a mental condition. This prosecutor has years of professional training which includes ethics courses. He knew exactly what he was doing. He wanted the conviction to appear tough, and damn the consequences.

I'd throw him in solitary for a year and never allow him access to a clock or calendar.
