There’s not much you can say about the tragic events at Virginia Tech yesterday. Just terrible, awful stuff.
But I would note this: After Australia’s Port Arthur massacre in 1996, the State and Federal governments moved to ban a large number of weapons, and tighten controls on others. Since then, there has been no mass shootings in Australia (though the Monash shootings, killing 2, might have been the next had bystanders not intervened).
Sadly it seems such a solution in the USA is impossible — both in political and practical terms.
