Mark Jenkins (L), an opponent of Arizona Senate Bill 1070 and Blake Sutherland, a supporter of the bill, discuss their opposite viewpoints outside the U.S. Supreme Court in Washington in this April 25, 2012 file photo. As the U.S. Supreme Court readies a decision on Arizona's tough immigration law, the consensus among advocates on both sides is that at least part of the measure will be upheld. If that happens, a separate pending case might block the law from taking effect. Picture taken April 25, 2012. REUTERS/Gary Cameron/Files (UNITED STATES - Tags: SOCIETY IMMIGRATION)
