After the bloody Virginia Tech gun shoot incident, another fatal gun shooting case happened at Northern Illinios University resulting 6 persons dead.

Yahoo News: 6 dead in N. Illinois U. hall shooting
CNN News: 6 shot dead, including gunman, at Northern Illinois University

This is also the fourth shooting case in US schools within this week.

I think the US government really need to seriously consider the total firearm bans in the country to avoid such incidents to happen in the future.
