The composer Frank Ticheli wrote "An American Elegy" in memory of the shooting at Columbine. (https://www.youtube.com/watch?v=YIIKdBYfmlo)

He relates an incident when he was talking to a conductor who was preparing the piece:

“He said to me, ‘I’m performing your ‘Elegy’ at Carnegie Hall in memory of the victims of the latest school shooting.’ And I said 'Which one?’ He said, 'The one that will happen between now and the Carnegie Hall concert.' Two days later, 17 students and staff members were killed at Stoneman Douglas High School in Parkland, Florida."

I'm getting to be an old man, but I get pissed off at my peers. We made a scary and downright ugly world for you to inhabit, I'm not sure we get to crique how you handled that.
