While living in Los Angeles, I attended a couple of anti-war marches on those periodic days of action that the U.S. anti-war movement has. I was disappointed that a city of 13 million people would only get a few thousand out to oppose the war. That's why it was very heartening to see photos like this and this -- there is a horrid anti-immigrant bill making its way through the U.S. Congress at the moment, and somewhere between half a million and a million people showed up in Los Angeles recently to oppose it. Here is a link to more photos and some reports of the action.
I especially like the message in this photo.
