In light of the commentary following, I guess the appropriate response is to feel somewhat sorry for the (probably relatively high proportion) of Americans who fully understand why other countries think their attitude to gun control is absurd.
Here's the best piece I have read:
The Most Dangerous Belief is not Believing in Gun Control
Here's an extract:
I actually think that there was some rhetoric that contributed to the shooting. Rhetoric like “guns don’t kill people, people kill people,” and “The only thing that stops a bad guy with a gun is a good guy with a gun.” Did you know that less than a month before the Planned Parenthood shooting, there was another mass killing in the town of Colorado Springs? One woman was witness to both, by the way, and her boyfriend said she cried the first time but not this time because quote, “She’s a veteran now.”
Well in that first shooting the shooter was walking down the street with his rifle—an AR-15, in fact. Concerned citizens saw him and called the authorities and said, “There’s a man walking down the street with a rifle.” And the dispatcher told these citizens, “Well there’s nothing we can do about that because Colorado is an open carry state and the only thing that’s going to stop a bad guy with a gun is—” Oh too late, three innocent people are now dead.
That was Halloween day. In between that mass shooting and the Planned Parenthood Black Friday mass shooting, the website Shooting Tracker chronicled 31 additional mass shootings. Forty-seven dead and scores more wounded. Now these were just the mass shootings. These were not the one-off accidents, the suicides, the targeted slayings, the gangland beefs. No presidential candidates of either party were called on to make statements decrying the Ohio man who killed his neighbors and their 7-year-old son; the quadruple murderer in Kentucky who shot a family then burned their house; the Texas man who shot six at a campsite; the Jacksonville, Florida, man who made the mother of his 5-month-old twins hold their babies as he shot her, and them, and then himself.
Guns. A lot of people have a lot of terrible ideas: Sometimes it’s getting revenge on an ideology, sometimes it’s getting revenge on the police, sometimes it’s getting revenge on people you personally know. But without guns, the death toll would be much lower. I’m not saying that all the hateful rhetoric around Planned Parenthood didn’t unfairly nudge them closer to the crosshairs. But it’s not just bad ideas and angry men that lead to these obscene death tolls. It’s that the ill heads with these twisted ideas can so easily access a means of lethality uncommon in the civilized world. We are an aggrieved, worked up, angry people. But an American who is aggrieved or enraged or unmoored is more deadly that an Englishman or an Australian not because of the extremes of our discourse, or the extent of our aggrievement. The bad idea that people are most dying from is not an anti-abortion idea or an anti-cop idea or anti-Western, anti-Christian. It’s anti–gun control. That’s the deadliest and most ignorant idea of all.
Obvious, but a large slab of Americans need to be reminded. (Depressingly, they'll also ignore it.)
In other commentary, James Fallows writes touchingly of how saddened he is by this latest shooting.
And from an article that appeared just before the shooting, here's an article ripping into the deliberately intimidating tactics of many "open carry" advocates: Gun Nuts Are a Threat to Democracy.
