Mentions of April 16

One of the things that dawned on me today while I was listening to my professor lecture today, is what is the limit of mentioning tragedy?

Everyone here is well aware of the tragedy that occurred here, and the underlying question is how much should we bring it up? My professor talked about an example relating to April 16th. As i sat back in my seat, I nonchalantly turned my head back to see if there was anyone talking to each other, looking upset, amongst other reactions. Thankfully I did not see it, but it still has bothered me that the example keeps coming up from time to time

I know personally that I have upset students in the past by bringing it up. They got emotional and I was the bad guy even though I didnt go in with poor intentions. This is something to consider when you have tragedy on campus I think.

Granted, my professor is dealing with freshman, so it may not be as bad to talk to them about it, but it sill makes me wonder how much should be disclosed
