Illinois shooting

Now another gunman went berserk in Northern University of Illinois and killed at least six students and injured more than a dozen before shooting himself. What we gather from the news is that gunman Steven Kazmicrzak had a mental problem and was on medication for sometime and was also receiving counselling; otherwise according to friends and teachers he seemed to be quite a good natured student and had no criminal records. Now the question that remains to be resolved is what prompted Kazmicrzak to take such hostile actions? A similar incident happened in Varginia Tech a couple of months ago where student Seung-Hui Cho killed as many students during his stooting spree. May we suggest that the authorities in the USA re-examine the gun control law and make it stricter so that guns don't fall in wrong hands.
