Yup, honestly how many times have you heard on a news report of some serial killer where they interviewed the neighbors, "Oh, seemed like a nice kid."You cannot know someone by seeing their face, but people like to believe that they can, and prefer to live under the illusion that seeing someone's face is necessary to know something about them.
Its like: You've been living next to this person for three decades, yet they had no idea that a serial killer was living right next door. You had no idea that the BBQ ribs you had at his cookout last 4th July were his aunt Sally's, whom he kept in the deep freezer for six months.
I don't mean any hurtfulness by my next statement, but we're seeing this right now in Ukraine. How many reports have you heard that said, "Oh, Putin never would have done this five years ago! This must not be the same Putin!" Really!? How can you possibly know that? Well, they looked at the poster boy photos of Putin and thought they knew who he was just by the look on his face. That same face threatens a nuclear assault.
