Jail over scandal?
I hope no one.
If they do go to jail, it should be for a crime. A scandal is a public embarrassment, such as when Tiger Woods was caught by his wife while cheating on her. Some states used to make that a crime, but no one wanted him to go to jail. He lost some endorsements and his swing, for a while, but he didn't commit a crime.
It's up to Congress to make a law that prevents such targeting of groups by the IRS, if there isn't such a law already. Let's make sure that is taken care of, Mr. Speaker.
As for firings, as many want, yes, that's appropriate for public embarrassment or hurting the trust people should have in your organization.
