No,
As the statement you quoted points out and what I'm suggesting is that when under pressure people they expose their real feeling - racial or otherwise - history show it to be true. I think it should be addressed in the school so history does not repeat itself.
It doesn't work to say that a white woman in a skirt or white male in blue jeans could be subsituted with Asian.
I read KM's statement to mean that people all hopped up on adrenaline and itching to be a hero would hear the rumor that an asian guy had done the shooting and would have a jumpy trigger finger when they saw an asian person. That doesn't mean they are racist, it just means they are not trained peace officers and therefore could react erratically and jump to conclusions in the heat of the moment, and should not be carrying guns around when they don't know what they are doing. People might be just as trigger happy if KM had said the shooter was a white male with a blond beard, since that description could similarly stand out from the general college population.
