Every time there’s a massacre at a school, like the recent one in Oregon, it reignites the debate for more gun control — not only because of the mass shootings, but because of the hundreds of incidents of gun violence every day on our streets and in our homes. One idea that keeps coming up is smart guns. These are firearms that only work when they’re fired by their owner. It seems that “gee whiz” technology is seeping into every corner of our lives. Why not guns?
