Kudos to the ACLU for this[ new video](http://www.aclu.org/blog/immigrants-rights-racial-justice/would-you-ask-...) exposing the racist underpinnings driving Arizona's SB 1070 law, portions of which were [temporarily halted](http://colorlines.com/archives/2010/07/breaking_arizona_judge_blocks_por...) today by a federal judge. The two-minute video shows an older brown man doing yardwork in Arizona. He's done this kind of work for 15 years, he tells us, but SB 1070 makes him afraid that because of the color of his skin and his work, he'll be asked to prove his citizenship status. The catch? The brown man is the president of the board of directors for the ACLU in Arizona, Roberto Reveles. That's probably his own yard he's cleaning. But the message is clear. Unless SB1070 is dismissed by the federal courts, anyone who's brown remains vulnerable.
