If it is him I would want him sentenced to the following:
1. Banned from clerking/working in or holding any government associated legal / judicial office - for life.
2. Six years of REAL public service. Specifically, having to work as a public defender in a poor urban area - excluding handing immigration or asylum cases.
3. Banned from writing a book about anything he was involved in at the SC - including the leak.
I have a simpler punishment in mind.
Really like #3. He gain no financial wealth from any book.
