Best say nowt?

A lorry driver working for a local firm who was on his way back from a trip to France was alerted by noises coming from the back of his vehicle.  He stopped and notified the police.  They turned up and when the back of his lorry was opened up 13 illegal immigrants were found hiding there.  You would think the driver behaved correctly and should be applauded - yes?  Well, no apparently.  The firm has been fined some £18,000 for "failing to carry out the necessary checks".  There's got to be something wrong here, surely?  As was pointed out, had the driver simply opened up his lorry and let them go no-one would have been any the wiser.  So this is one of those areas where you are punished for doing the right thing?  Crazy!
