Parenting Skill

When I first saw this a week or so ago, I laughed really hard. This father posted a photo of his badly scribbled/drawn/vandalised passport with a caption saying he's stuck at the airport thanks to his son. After the initial laughing, I couldn't help but think, why would anyone leave important things like passport within reach of children? Why didn't he check his passport earlier before he left for the airport? Did the child receive any punishment for vandalising? Is it right for current day parenting to eliminate spanking and disciplining altogether? How would you react if you are in this parent's shoes?
