The victims probably don't fit the affluent, white school children profile the media loves to turn into a human tragedy of epic magnitude. Most of them were probably like Mr. Shaw: a member of an ethnic minority in the middle or lower middle class. That makes them page twelve, not front page material. In other words, if it's white it's up front, if it's black it's in the back. Sound familiar?
If Mr. Shaw had used a legally possessed weapon to end the confrontation the incident would have garnered a mention on the morning news, if that.
