Angus already mentioned this.
But you may not have read the story. Excerpt:
From California to Massachusetts, districts are hiring special investigators to follow children from school to their homes to determine their true residences and decide if they "belong" at high-achieving public schools. School districts in Florida, Pennsylvania and New Jersey all boasted recently about new address-verification programs designed to pull up their drawbridges and keep "illegal students" from entering their gates.
Other school districts use services like VerifyResidence.com, which provides "the latest in covert video technology and digital photographic equipment to photograph, videotape, and document" children going from their house to school. School districts can enroll in the company's rewards program, which awards anonymous tipsters $250 checks for reporting out-of-district students.
Only in a world where irony is dead could people not marvel at concerned parents being prosecuted for stealing a free public education for their children.
The only way the teachers' union, the AFT, can keep a lid on this is to keep parents "away from the table." The solution, as I said when I ran in 2008, is means tested voucher. The wealthy have choices now. It's the poor folks who need help.
As it is, we are just putting people in jail for "stealing" what all my leftoid friends assure me is a public good.
