@ossobuco,
Good comment from Gopnik:
" So let’s state the plain facts one more time, so that they can’t be mistaken: Gun massacres have happened many times in many countries, and in every other country, gun laws have been tightened to reflect the tragedy and the tragic knowledge of its citizens afterward. In every other country, gun massacres have subsequently become rare. In America alone, gun massacres, most often of children, happen with hideous regularity, and they happen with hideous regularity because guns are hideously and regularly available.
The people who fight and lobby and legislate to make guns regularly available are complicit in the murder of those children."
The responsibility for these children's deaths can be laid at the feet of the gun lobby, the "cold, dead hands" fraternity.
