Well, the title certainly applies to the San Bernadino shooters, but in this particular case, it doesn't.
You may or may not be surprised to find that it in fact applies to me. Apparently, I am a "cold-hearted monster" "indifferent to loss of life". What could I have done to earn these appellation? I objected to the President's proposal to strip citizens of their Fifth Amendment rights to due process because they're on a "No Fly List". After asserting what it is that I object to (the arbitrary removal of civil rights on the say so of an unelected bureaucrat), I was told that I must come up with an alternative solution then. Otherwise I am... I am unsure... wrong? Bad? Irresponsible? It was never made clear to me. So I gave my response. "Nothing" would be a better solution than this. And to borrow from an old joke, "that's when the fight started".*
I was told, "no, what is your proposal". I reiterated, "changing nothing, doing nothing, passing no new laws" is my solution. "We need an answer" was the response. So I made a third swing at it, backed up with facts. The US has, by far and away, more guns per capita than any other nation on earth (about 112 per 100 people). And yet, contrary to what the pundits will tell you, we are only 111th among nations in homicides (and for the record, that's ALL homicides, not just gun related homicides) at approximately 4.6 per 100,000. So on average, we have 4.6 deaths per 112,000 guns. That's 4.11x10^-5 deaths per gun. When you must put your answer in scientific notation, you know that it's either REALLY big, or really small (0.00000411 per gun). And again, that assumes that each homicide is committed with a gun (which they are certainly not). Furthermore, this number is on the decline.
Given the already low number of deaths, and the declining nature of the problem, I would say that doing precisely nothing is a workable "solution" to the problem. And there you have it. I am a "cold-hearted monster" and "indifferent to loss of life". Because I refuse to offer any solution. So I stand before you, a monster. And I await your scornful judgment.
* The joke goes:
I walked into a bar, and these three rather fat women were talking by the bartender, and I noticed they had accents. So I said "Excuse me ladies, are you from England?" The largest one shouted angrily at me, "Wales, ye daft fool! It's Wales!" So I apologized profusely, "I am terribly sorry. Are you whales from England?" And that's when the fight started.
