RIOT wheel
Okay, so a "riot wheel" is a thing that some police use to control groups of people who are being very energetic and moving around a lot (like in a crowd). The wheel is basically a moving fence made of connected panels or bars that are pushed by the police.
The idea is that the wheel can move in a way that keeps people from going where they're not supposed to go, like onto a street that's closed for the police to work, or into an area where they could get hurt. The police can use the riot wheel to make a path for themselves to move through the crowd, or to keep other people away from something that they want to protect.
The riot wheel is kind of like a giant monster truck tire, except it's not actually made of rubber and doesn't have any treads. It's made to be sturdy so that people can't push it over or knock it down, and it can be moved around as needed. Sometimes people climb over it or try to push through, but the police try to use the wheel to stay in control and make sure everything stays safe.
