Something You Don't See Every Day - A Mass Stabbing Attack

CNN reports

Three people were in critical condition and one in stable condition after a stabbing incident Wednesday afternoon in Columbus, Ohio, that ended with the suspect being shot by police, Columbus authorities said.
The attack began inside a downtown building that houses Miami-Jacobs Career College, said Columbus Police Sgt. Rich Weiner.
The stabbing victims in critical condition underwent surgery at Grant Medical Center, while the one with less serious injuries was taken to Mount Carmel West hospital, officials said. The suspect was in critical condition at Ohio State University's Wexner Medical Center, Weiner said.

The rarity of this type of incident should be enough to highlight what a terrible blight guns are on our society.
