To the degree that we're talking about actual newsPAPERS (and the use of the term "front page" leads me to believe she is), this is probably a simple question of space. If one guy shoots another, you can probably run photos of both. But if one guy shoots 10, a photo of one shooter takes up a lot fewer column-inches than photos of 10 victims. If you're really intent on running photos of all 10 victims, you'll probably scale them down, maybe arrange them 5 x 2 in one panel that's collectively larger than one shooter-photo but smaller individually. In other words, mass-shooting victims are pictured less often, and smaller, for the simple reason that there are more of them. Maybe not the best reason, but that's precisely my point; no editor decides like "Hey the shooter is way more important and awesome, let's run his photo up front, and fuck the victims amirite!?"
