Someone (I can't recall who) warned years ago that we were raising a generation or two of 'super-predators'...looks like that time has arrived.
This concerns me, not only because of what it is, but should there ever be a breakdown of society, there will be these types of soulless, sociopaths roaming the streets looking for food, shelter, and whatever else you have that they don't.
It's going to be shoot to kill time.
