A 26-year-old man went on a shooting rampage at a college in Oregon killing 10 people and injuring 9 others. 

Oregon is one of the states where campus carry is legal under certain stipulations. Everyone with a concealed firearms license is allowed to bring guns on campus.

That is because a 1989 Oregon law forbids any public body except the Legislature from restricting the rights of concealed weapons permit-holders to bring guns where they wish.
