Well it is indeed staggering how they manage it and fascinating too, i myself would make the worlds worst thief as i have a sign saying 'guilty' on my forhead. I always feel amazingly guilty walking through the customs for example even though I have nothing, how they never pull me over I dont know...thats a headscratcher that is!
But fascinating to see that despite all the prohibitions in place these days people can still do it..plenty of Artful Dodgers about it seems.
