With all due respect, I really wonder how much grieving I can do for people whose names I never even knew until this morning. There's authentic emotion, and then there's the synthetic kind which intellectually intimidated people like using in order to belittle those who are intellectually capable of thinking up solutions to prevent future tragedies.
Technically-knowledgeable people often respond to tragic circumstances by trying to think up solutions. This is not coldly insensitive; it is wonderfully appropriate. And in its own way, it is the sincerest form of demonstrating true grief.
