The problem is that nothing comes before money - so the child is too young at 9 years old - Seaside Tours must have been sweating at the thought of losing the rest of the family booking so turned a blind eye. Then, full in the knowledge they sold a ticket that directly caused a child's death, they did the same again to undercover reporters from the UK.
Same with the repulsive dolphin tank in Hisaronu - while so many tour shops refused to sell tickets, some couldn't restrain themselves and put a few quid over the plight of the animals (and the plight of customers going to 'swim' in water full of dolphin poo). It seems to me that they will always find a way around it if there is a few lira to be made. That's just the way it is over there.
Jail sentences and licenses being revoked is a step in the right direction - but this is all addressing the companies that provide the excursion, while those who sell the excursion can carry on doing so, and experience shows will do so.
