So, where are the high-tech solutions in this conflict with terrorists, plotters and evildoers? Surely a nation that can produce iPods, cell phones, gigabit data streams, server farms and laser-guided bombs can sniff out some bad stuff without banning every water bottle and toothpaste tube from air travelers. Our soldiers are struggling mightily with a similar problem, trying to detect improvised explosive devices. Putting policy implications and opportunities for political mischief aside, why don’t we have high-tech sensors and sniffers—electronic moats and virtual walls—to protect citizens and soldiers from bad guys and bad stuff?
Technology is not a magic bullet that will render impotent all threats. But the nascent security tech revolution will make us safer, and soon.
