A lot of people have opinions about whether or not having a gun has any correlation to shooting a gun at other people. With the shooting at Umpqua Community College, those opinions are being typed about in a fever pitch on message boards across America. Who in our government might do some research to explore the problem of mass shootings? Perhaps...scientists? Or more specifically the CDC, or Centers for Disease Control and Prevention? They're the people charged with making sure we know that smoking causes cancer. But there's a problem! The CDC is literally banned from doing any scientific research on the relationship between gun ownership and gun violence.
