Perhaps you're right. I think within the revised manual it may be slightly stronger, but we're talking there generally about surveillance techniques, and if you had secret filming that was surveillance, in itself that may not be illegal. It may not be a criminal offence. So it was giving the basic point that telephone tapping and everything else, that can amount to a criminal offence and should be avoided. Really, that's a clear warning to any journalist to stay clear of it unless you're very certain and taking proper advice.
