What is worth rioting for?

In Terhan, Iran, thousands of people are rioting because they are frustrated with what appears to be a heavily rigged election. So far, as of today, I have heard there is a death count of 7, with pro-Ahmenijhad troops firing into unarmed crowds. Who knows how many have been injured, arrested, beaten, torured.

In Los Angeles, California, fans riot in the streets to celebrate the Lakers winning.

These two places are on opposite ends of the Earth, literally and figuratively.
