An easy way to find illegal aliens

The new Alabama law shows that illegals respond to incentives. Will the schools look at those who started not showing up to school after the judge's decision? From the Associated Press:

Education officials say scores of immigrant families have withdrawn their children from classes or kept them home this week, afraid that sending the kids to school would draw attention from authorities.
There are no precise statewide numbers. But several districts with large immigrant enrollments -- from small towns to large urban districts -- reported a sudden exodus of children of Hispanic parents, some of whom told officials they planned to leave the state to avoid trouble with the law, which requires schools to check students' immigration status.
The anxiety has become so intense that the superintendent in one of the state's largest cities, Huntsville, went on a Spanish-language television show Thursday to try to calm widespread worries. . . .
