They say it was common for professors to call on Cho and for him to remain silent. The teachers would become angry, and students would taunt him.

Since when?  When does this happen, in multiple classrooms of a college?  

If it were true, this sentence would be an indictment of Virginia Tech. 

I don't believe it.  I call horsesh!t on the whole article.

I don’t get your point. Are you speculating that students and professors wouldn’t be so “uncaring”?
