The media loves this kind of stuff because it generates so many viewers. The problem is that they capitalize on every bit of violence, and they try to draw in as many viewers as possible. This tends to lead to overblowing every single story that involves children, bombings, mass murder, etc. Why? Because the American public loves it, not so much in the sense that it makes them happy but in that they will watch it, cry a few tears, and then move on. In order to make the story more newsworthy, then what better than adding some jihadist terrorists in the mix? Because everyone knows that's bound to attract attention, even if it is patently false.
