Isn't it funny how everyone sees different stuff in that picture? It's like a psychological experiment - what do you see here?
I see an angry looking strong young man walking at a good clip toward a group of cops who have their guns raised. Looks to me like it's possible he wouldn't stop approaching even when told repeatedly.
