Since the law has come into force in july, the number of 6 you've mentioned represents all the tourists that the police had to 'explain' the rules to, because they were walking around with their burqas ON -- it might also be worth mentioning that when the police actually showed up and talked to their respective husbands, all of them not only put the burqas down like it's no problem, but they also reacted politely and some of them even apologized.
But this is NOT counting the ones who put their burqas down before they entered the region! How many these are we don't know, but the association of hoteliers confirms that the predicted decline of tourists from Arabic countries didn't occur, in fact that there's an increase of tourists from these regions by 20%, and that they're understanding towards the law.
So to say that the example is only about 6 people is a gross oversimplification.
