Somebody on that comment section of that Yahoo article was accurate when they stated that all the sadistic psychopaths and sociopaths will come out of the woodwork to "feed" on the fear, pain, and misery of the victims families...
The thing that most normal human beings have a hard time comprehending is that these "creatures" that appear to look like human beings, and in many cases can "fake" basic traits of as well are actually proven to have a different wiring pattern in their brains...these people have no empathy, believe that others are there strictly to serve their needs, and have NO conscience at all. The lack "humanity", even though they appear to be human.
I think when a lot of people speak of "reptilians" they are referring to these types of people.
