The Dennis Hastert case, you'll recall, was a good example of this. He's sitting in prison at this very moment, you would say, because the "banks' practice" "forced" him to break out his withdrawals into less than $10,000 nuggets.

This case was a little bit extreme, especially when Hastert was told explicitly that reporting is required and still do so.
