It's clear as Mudd to me.

Eight months after his talk, Mr. Mudd admits that some in the bureau do not accept his guiding premise: that arresting bad guys is sometimes less important than collecting intelligence to uncover the next terrorist plot.

Or...wait...don't arrest the bad guys? OK. There might be a little problem with that.

Seems that this guy Mudd, a honcho from the bureau's National "Security" Branch, wants to re-shape the FBI as a "spy organization," according to the NYTimes. Some think that can't be done; some think it can be done, and only too well.
