At first glance it looks like the priest is trying to attack with the rioter who is getting ready to throw something. Then you see the police in the background, who are the intended target of this projectile. Finally, I realized he is trying to get in the middle of the conflict to help both parties. I'm guessing he's begging the guy throwing the object to back down, because it's not worth it. I can almost hear him imploring in my own ears.
This is a very bold image I won't soon forget. Maybe I'll try to step in and help diffuse a situation instead of inciting it further.
