It's sad to see Lula's government repeating prohibition's endlessly deranged logic.  Reducing suspicious flights only indicates a switch to alternate smuggling routes.  But interdiction proponents will claim any reduction in flights as proof of their success.  So until the political will is found to dismantle it, the machinery of death will remain.  If the system "works" it means arbitrary execution for drug suspects without a trace of legal proceeding.  That alone is intolerable.  But failure will only be recognized when another obviously "innocent" family, such as that of Veronica Bowers, is brought down from the sky and murdered.  Sunspots, poor vision, pilot error and mechanical problems make it inevitable.  Why such an event must happen before the shoot down policy is changed is an infuriating question.
