Currently few if any TSA airport sites use working dogs. Instead of spending millions on technology that cannot find everything, start placing trained bomb sniffing dogs at all airports. At the same time train TSA personnel to watch for signs of people reacting nervously to the dogs. These individuals, and any the dogs alert on, could then be rapidly pulled aside for enhanced security inspections. Utilization of properly trained dogs combined with other measures will identify more potential threats quickly and with less hassel to the travelers and at a lower cost to the taxpayer.
