Violence is never the answer:  Except when it is…
      

The platitude is dangerous.  On the one hand, when we transmit it, we transmit something we know is not actually true.  That's bad policy right there.  On the other hand, it shuts down an important area of human experience that requires extensive critical thinking.  In a world filled with evil and malignant men, every good person must be prepared in their mind for what they should do given certain eventualities... because we know from the newspaper and history book that these things do happen.  Another danger to the platitude is that it sets people up for guilt after they perform a violent- but righteous- act.  Finally, if someone has never actually thought about the matter before and all they've been fed is the platitude, they might freeze up and do nothing, or flee when they should fight.

I can think of no better example then the story that emerged out of the Virginia Tech massacre of Liviu Librescu.  Here is a survivor of the holocaust, gunned down through the door that he refused to open for the gunman.
