If you want to change the world, writes Steven Greenhut, you need to start in your city. A great example of what agitated citizens can accomplish is taking place in the Southern California city of Fullerton. Three council members are the targets of a recall election on June 5. The effort has gained steam after the Orange County district attorney recently released a horrific 33-minute video of the city's police officers beating a frail homeless man named Kelly Thomas last July. Thomas later died in a hospital. These three council members opposed the release of the video to the public.
