Option 2; most mass shootings (a guy killing thee people in his office, etc) don't get much attention, but when the victims are children it irks me a bit. The UCSB shooting didn't even bother me at all (I assumed it was gang/crime related due to the first reports saying it was a drive-by) until I read the manifesto and saw how evil and twisted Elliot Rodger really was.
The overwhelming majority of murders have nothing to do with mass shootings; the latter get more attention because they're liable to involve upper-middle class white people.
A rare sage post that is somewhat true.
