usually i'm not a big fan of photos of protest signs, because it's usually the photographer making the subject do all the work of being witty, etc. but this one is great. the anonymous finger coming in from the side really adds a meaningful punch and makes the photo work for me. great shot.
Hehehe, I like how funny this is and you didn't even realise how funny it was. I thought everyone knew police were reffered to as pigs (chief wiggum from the simpsons has a snout for example?) Anyway, the fact that you saw a good photo and took it reguardless of a deep understanding of the subject matter shows that you are quite a good photograhper. Perfect timing and composition.
I'm almost certain this man is trying to say that People act like pigs. Have you ever heard the phrase "The pigs of war"? George Bush is no human, he is a pig. Anyways, Great capture. I love this shot. :]
