WHERE to start. What you are seeing above is a motorcycle-mounted Luchador wrestler charging at and being fired upon by riot police. Which is pretty much what went down.
The image has been circulating Reddit and shows the Lucha Libre wrestler onboard a cruiser sporting an SME logo, an electrical union that has been banned in Mexico. The riot was in Mexico City and is part of ongoing protests that have been taking place since 2009, after the workers jobs and union were taken away by Presidential decree.
