For long-term thinkers, the most alarming part of our failure to have the right conversation about the causes of predatory mass killings is that our civil liberties are put at risk. The seductive anodynes put forth by short-term thinkers require that law-abiding citizens sacrifice their own freedoms in a well-meaning but clearly improbable effort to stuff the predator genie back into the bottle.
There can be little doubt that Homo Sapiens is the most dangerous predator the world has ever produced. We have enormous brains capable of building systems to overcome friction, the ability to accomplish complex planning within those systems, and opposable thumbs to assist in the execution of the plan. We have canine teeth and forward-looking eyes. We are the most accomplished killers in the animal kingdom, exceptional when hunting alone, but capable of cooperating in large groups to make a kill.
