I was out grocery shopping when the news on the giant store monitor hit: Once again, there had been shootings at Virginia Tech, in Blacksburg, Virginia, 40 miles southwest of Roanoke. The last bloodbath there was in 2007, involving some 30 students at the hands of Seung Hui Cho, who apparently fell through the cracks of an, as-usual, clueless mental health system. This time only two had been shot (as of 5 p.m., Thursday, December 8), including a campus security cop. The shooter is either dead or at large — law-enforcement officers are unsure at this time whether the second body found is the shooter’s. But as everyone knows, ever since Columbine in Littleton, Colorado, school shootings and other violent acts, such as rapes on school property, seemed to spur a rash of similar crimes, despite draconian security measures: pro forma backpack checks; random locker searches; lockdowns (reminiscent of a prison setting) at the merest suggestion of mayhem; police roaming rooftops; bans on any depiction that might resemble a gun, insignia, or even a patriotic hat; mandatory cellphones, distributed to students to alert them to the latest mayhem; and more. All for naught.
