Reply To: What is the appropriate punishment for financial crimes?

EretzHaK – That only applies when a Yid has a financial crime against another Yid (which is the case of Rav Moshe), and only when you can fix the situation in Bais Din (as Rav Moshe explicitly states). When the crime is against the US government (or an Aino Yehudi), none of that applies.

Besides, you haven’t addressed the Mored B’malchus aspect, which is (hypothetically) outside the jurisdiction of Batei Dinim.
