Father Punishes Son For Being A Bully

As a punishment for his son bullying another child, this Texas father made his kid stand on the street corner holding a sign that said “I Am A Bully, Honk If You Hate Bullies”.

There have been mixed feelings from the public on if the father should be applauded for doing this or if he over-reacted and shouldn't have humiliated his son like this.

What do you think? Does the punishment fit the crime?
