captaindejavu,
mate as far as i know 'goods' mean anything that you bring into the country.
that means laptops,your shaver,your hairbrush or the latest car magazine.i don't think customs are interested in a letter your girlfriend emailed you or a word document that you are sending to your solicitor.
it sounds like someone didn't share this blokes taste in porno and dobbed him in and bingo the boys nabbed him.
the problem is that if it wasn't for dopes who try to do this stuff the rest of us who are not doing anything illegal would be able to walk straight through customs in minutes.
