Not the same thing
I get it. I really do. It was traumatic. People are shaken up. Two men are dead.
What's the value of the "it's happened again!!" hysteria at Virginia Tech? The "violence rocks the campus again" headlines?
Four years ago, a severely disturbed student started shooting other students and professors in a class building. Yesterday, somebody shot a cop during a traffic stop.
These are not the same kind of occurrences. Except for the location, and the ubiquity of guns, they really have nothing in common. And the second one is far, far too frequent.
