I hold no brief for either Iraqi war or this past Virginia Tech murderer's brandishing of his anger, or I should say, of his parody.  
Does any of you notice that?  
This tragedy implied the contradictory parts of the advent of technology.  

News can freely broadcast the murderer's testament in the recordings and pictures throughout the world, but the in-time spreading warning to escape and in-needs of rescuing within an acres campus could not succeed.  

In addition, 

some of the victims, sarcastically while they were alive, sent text messages through cell phones across the buildings of V.T. campus, none of them walked out of the scene themselves; media, aggressively, spread the murderer's unsettling writings and his pre-recorded video through cyber network in the information-sharing signals.  

The shooting proved the limits of the hardwares; however, it was successfully crashing human's soft hearts and conscious souls.
