In Colorado, gunman kills hostage, self in standoff(Sep 29)

My Opinion
I think gun must have disappear in this world. If gun were not made at the first time, nowadays were not happen same situation. Of course someone said it must need as protect by themselves. But I think gun is more and more happen to the bad accident. This accident's gunman is very bad guy. Why he was kills hostage. What a shame. Also I wonder that why Platte Canyon High School supervisor didn't defended the gunman. They must keep away from stranger.
