If Only...

If only there were a real-life example of what happens when a community decides to start treating its minority population like shit, violating their constitutional rights by pulling them over demanding proof of residency without cause and so-forth, you know, like the state of Arizona is about to do, like, if there were perhaps dire economic consequences of such an action, as in, half your county moves out and takes their economic power with them. If only there were such a real-life example, and if only someone had thought to make a movie of said example.
