I ALWAYS speak up now.  I don't want to be someone's victim.  Twice now I've reported suspicious packages at the Post Office.  A guy came in, dropped a parcel on the desk, and left.  I immediately spoke up.  Turns out, he had a girlfriend in line and she was mailing it.  But you never know.  Better off safe than dead or maimed.
