In the 60s I saw children being raised by well-meaning hippy parents - "Ooo, don't mind Justine, she's just highly spirited!" (Crash.) "Please don't shout at Tarquin, he's just being creative." (Crash.)
Justine and Tarquin, needless to say, turned out to be grown-up brats, and had brats of their own.
Discipline (which can mean a sharp smack of correction) is how young animals are raised, tempered by love and kindness.
The bus driver will probably be sacked, but (curiously) I'm with Theland - he deserves a medal.
