Lost proportionality?
How much money would consider to be fair compensation for what has occurred to this man because the Police intentionally withheld information that would have exonerated him?
I agree with you. The award should be $180 million. And not only that, the scumbag sheriff and the scumbag prosecutor should do some hard time.
A lawyer friend once told me that if you believe that the "compensation" is the correct amount for the injury, ask yourself the question, "what would I agree to in advance to suffer that injury?". Go ahead and include an amount for the difference between knowing it's going to happen and being surprised.
The actual "fair compensation" via this little thought experiment is typically much less than this kind of award.
