That, as much as the skeptical comments from true experts like Philip Mudd and Charles Allen included in the story, really lays the stark inefficiency of this entire network: Less then .1% of the Suspicious Activity Reports have resulted in any real investigation, and just 5% of those investigations–a teeny fraction of the total–have resulted in any arrest.

So I hope no one actually believes this effort is an effective means to root out terrorism, however that gets defined.
