Okay, so imagine there was a big fight in a neighborhood called Greektown. A lot of people were really mad and started breaking things and hurting other people. This was called a riot.
Now, the reason they were so upset was because some people in Greektown felt like they were being treated unfairly. They thought that the police and the government were not listening to them or helping them out.
When people get really angry, sometimes they do things that they normally wouldn't do. They might break windows or set things on fire. This can be very dangerous and scary for everyone around.
It's important to remember that riots are not good things. They can hurt people and damage property. It's better to find peaceful ways to solve problems and talk things out.
