Sources say psychopaths drink water regularly, which can't be ruled out as a catalyst.
In interviewing these people, we get two consistent descriptions that always show up in every single catastrophe. They'll either say that they couldn't believe that he did it because he was such an outgoing, friendly guy -- you'd never expect that he was secretly a ticking time bomb of taco-stand annihilation. Or they'll talk endlessly about how he was a quiet loner. Always kept to himself, obviously plotting the demise of coffee shops and cellphone cover booths.
It's always bothered me that the news devotes so much time to their social status. I mean, I understand why they do it. We want an explanation so we can understand what made Chad Angrytank finally pop and whip out his tank fury. And for some reason, it's just not enough for us to settle on, "He had obvious mental problems. Sane people don't go on murder rampages." It's just always been weird to me that they choose that specific area of his life to examine, barely branching out to other possibilities or clues.
Can you spot the ticking time bomb?
But over time, we've seen so many of these "He was a loner time bomb" stories that we've started to associate completely normal introverts with an inevitable madman demise. That dude isn't a human. He's an eventual headline. Even from a non-murder viewpoint, it's still hard to not be creeped out by introverts because our personalities and mental conditions are an unknown to people outside of our bubble.
