Was San Bernadino Islamic Terrorism, Workplace Violence or just a run-of-the-mill shoot 'em up? For some, it doesn't matter, as long as guns were involved, the evil isn't in the who and why but the how (while the Daily News has every right to offend, their cover today was disgusting).
There's no law that can keep us safe. After all, there are laws against bombs. Still, the Bath School Massacre, Oklahoma City, Boston Marathon and a host of others, are all examples of how mass death can take place without guns. When deranged people have a goal, they will usually achieve that goal regardless of the laws in place.
Misguided folk, who believe laws can keep us safe, feel there are ways to keep guns out of the hands of 'deranged' people. Unfortunately, the definition of 'deranged' is likely to be open to political maneuvering. I know, because of my deep distrust and dislike of government, that I could easily land up on a politicized list of 'deranged' people. I don't want to invoke Godwin's Law, but it suits this discussion...the Nazis classified political opponents as 'mentally unstable'. Is it so hard to conceive of a future where people like climate skeptics (who are already hearing calls for their views to be criminalized) would be classified as 'mentally unstable' and have their guns taken?
Even more misguided is the belief that banning guns will make us safe. Because strict gun laws always make us perfectly safe. Like in Chicago. Or California. Or France.
To make a case compelling, you have to make it seem like science, so you'll call up data and misuse it. Which is what WaPo did on this blog. Alternatively, you can pick and choose your data to suit your meme. It doesn't have to be scientific. It just has to look scientific.
