There's clearly a USA/UK difference between the distinction of civil and criminal at play here. I mean, in the UK you don't get sued for criminal acts before getting criminally charged for it. If a British criminal court fails to successfully prosecute someone for an alleged crime, then as I understand it there is no hope of a civil case succeeding unless there is new evidence, and that new evidence would probably result in a criminal retrial before any civil proceedings took place.

There might be an element of a lower threshold of proof for civil courts that result in exceptions, and I might also just be flat out wrong, but morally speaking if someone is guilty of a crime they should face a criminal court before a civil court.
