Being investigated by the government or sued by a competitor can pose an existential threat to a business.  Even for companies with the luxury of in-house counsel, knowing the measure of the correct response is a difficult calculation.  The perspective of an objective third-party expert can help you avoid that zero-moment point where your options are narrowed or fate put in the hands of a judge, jury, or regulatory authority.

Likewise, the government needs experienced specialists to fill knowledge gaps.  Juries are significantly more receptive to the opinion of an outsider brought in for their unbiased opinion on a topic than they are to a duplicative parade of investigators trying to establish their command of a topic and not buckle under cross-examination.  When tens of thousands, hundreds of thousands, or millions of dollars are at stake in a criminal prosecution or civil asset forfeiture action, going into litigation without consulting with an acknowledged expert would be to court disaster.
