No one likes to look at the underlying causes of why some things happen, because bursting out in an emotional response is so much easier and attention-grabbing. Many of these causes and possible solutions would make many uncomfortable and likely cross their particular political and cultural sensitivities.
Mass shooting or homicide rate going up at a certain number? Let's BAN all guns! Of course, we cannot utter such crazy things such as if psychiatric drugs were involved, poverty rates, access to abortion and social service facilities, etc..... And God forbid someone say something along the lines of "no matter what, an occasional mass killing WILL happen, no matter what."
Insensitivity trumps logic nowadays.
