The types of technology that we use include VACIS machines, which are large scanning machines. You can put an entire tractor trailer through them, and they'll show up any anomalies in the consistency within the container. We also, of course, use detector dogs.
As equally important as the technology is the training of the officers. We continually issue intelligence alerts as to new indicators to look for, whether they be the particularities of the shipment or the behaviour of the individual.
