Iranian Court Punishes Vandals With Donkey Rides

I believe there already is some shaming going on in the US - there are some creative sentences wherein the perps are required to do stuff like take out an ad in the local paper, confessing to whatever the heck it is they did.

Eike von Repgow collected in the early 13th century some such sentences in Germany, called the "Sachsenspiegel" (German: "Saxon Mirror").

It was written originally in Latin and later in German and showed little Roman influence, largely because Roman law was still virtually unknown at that time and had not penetrated German law.

The Sachsenspiegel was used by many towns as the model for their constitutions and codes. Magdeburg's, known as the Magdeburger Recht, was copied throughout Germany and eastern Europe. Although some of its provisions were assailed by theologians in the 14th century, its influence was felt in German territories for more than 300 years, until the reception of Roman law in the 16th century.

Now, since we have Roman Law, such would be impossible here.

Exposure to public mockery seems an attractive punishment, but it's telling that no democracy uses it.

The only other two examples that come into my mind are:
1) The parading (with dunce hat and everything) of supposed "enemies of the people" during the outrageous Chinese Cultural Revolution in 1966-1970.
2) The exposure (with big posters of their faces in campus) of students who cheated at their exams in Havana's Polytechnical University (1979).

I think, such punishments may be efficient if being applied in a proper way. They should be applied to teenage perpetrators for small-scale misdemeanors. Teenagers are sensitive to being mocked, much more than the adults are, therefore possibility to having been punished in a humiliating way may be a good deterrent for such misdemeanors as drunk driving, brawls, sexual harassment of co-students (I do not mean rape or assault, these should be punished by jail term), vandalism, gross indecency, etc.
