Personally I feel that public humiliation is not the acceptable way of bringing the children back on track or preventing them from performing undesired activities. It is not done overnight, it's part of upbringing in a methodical manner right from the early stage. Children need to be disciplined when they commit mistakes. The prime objective as a parent is to make them understand that they are wrong and guide them to the correct way of doing things. Negligence from parents will allow more tolerance for children to commit much more serious mistakes and eventually parents will end up with such harsh punishments. If such punishments are repeated, I strongly believe that, it will have adverse effect on children's behaviour and moulding their individuality in society.
