As I develop more interest in security and its underlying systems, this story is both fascinating and disturbing. It boggles my mind that Homeland Security is monitoring random spots on the main freeway (north-south) through Washington (I5), and that they’re sensitive enough to detect radiation from a cat undergoing cancer treatment. I worry about the tighter net we cast, and, even more so, the underlying fear. Will we sell the soul of our society in a vain attempt to mollify our terror of terrorists? The thought that we’d, rather willingly, thrust ourselves into a Stalinist state rooted in distrust deeply saddens me.
