Tuesday, 7.30pm, Seven This show, hosted by Grant Bowler and in its 11th series, is a constant source of fascination. The subterfuge people use to sneak prohibited items — from drugs to seeds to granny’s homemade salami — through Customs is often ingenious. But their resourcefulness is no match for the clever detector dogs with their olfactory senses that range from 100,000 to one million times more sensitive than a human’s. When perpetrators are caught, often their reaction is pure theatre. Tonight a passenger becomes enraged when officers search him, and a nervous couple tries to dump something suspicious. And, yes, everyone filmed signs a consent form.
