Crime and punishment

Do you think punsihments in the USA fit the crimes? I'm sure that could be debated for months and months. However, here's a crime that was supposedly punished. This article states that:

The punishment was consistent with the California Education Code, officials said. They did not give further details because of legal and privacy issues.

Hmm. I agree with the writer, Michelle Malkin when she asks:

What are the odds that the guilty student and his/her collaborators are here illegally?

I'm wondering why the punishment doesn't include hanging the perpetrator(s) upside down on a flagpole for at least the same amount of time the US flag spent in that fashion?
