i made them stop googling

yesterday, i was teaching class when the news started coming out about the shooting. i told the kids to stop googling and pay attention to the class. i didn't realize the magnitude of the event and now i feel as though i acted like a cranky belligerent teacher. i think we'll discuss it in class tomorrow. especially considering that a korean kid was the shooter. what will this do for koreans living in the south. will we be vilified and racially profiled as criminals now?
