This is worth repeating. The FBI has determined that in some cases, it's better to let innocent people be assaulted, murdered, or wrongly sent to prison than to halt a drug investigation involving one of its confidential informants.

Could Murphy assure the U.S. Congress, Delahunt and Lundgren asked, that the FBI has since instituted policies to ensure that kind of thing never happens again?

Murphy hemmed and hawed, but ultimately said that he could not make any such assurance. That in itself should have been huge news.

So why wasn't it?
