I never understood this one. Bonnie and Clyde were mass killers. That entire gang was nuts. Yet society venerates and glorifies them, makes films about them, and they are almost iconic lore. We glorify mass killers like Jesse James as if they are a celebrity.
Yet we see a mass shooter every once in a while, and we denounce them and wonder why they did it, and how could they do such a thing...
And then we have no problems with massive media coverage of the shooting, which some can misconstrue as glorifying the event. And some crazies who view the media coverage and things like Bonnie and Clyde coverage as glorifying will be convinced to shoot people as well. They hope they get a film made about them someday, perhaps.
It all seems really screwed up.
