DOJ's absurd argument against Louisiana's school voucher system

NOLA:

The U.S. Justice Department is suing Louisiana in New Orleans federal court to block 2014-15 vouchers for students in public school systems that are under federal desegregation orders. The first year of private school vouchers "impeded the desegregation process," the federal government says.

Thirty-four school systems could be affected, including those of Jefferson, Plaquemines, St. John the Baptist and St. Tammany parishes. Under the lawsuit, the state would be barred from assigning students in those systems to private schools unless a federal judge agreed to it. A court hearing is tentatively set for Sept. 19.

The statewide voucher program, officially called the Louisiana Scholarship Program, lets low-income students in public schools graded C, D or F attend private schools at taxpayer expense. This year, 22 of the 34 systems under desegregation orders are sending some students to private schools on vouchers.

State Education Superintendent John White took issue with the suit's primary argument and its characterization of the program. Almost all the students using vouchers are black, he said. Given that framework, "it's a little ridiculous" to argue that students' departure to voucher schools makes their home school systems less white, he said. He also thought it ironic that rules set up to combat racism were being called on to keep black students in failing schools.

There is much more.

The only way this suit makes any sense is as a sop to the teacher's unions who want to keep children captive to their failing schools.  The vouchers are color blind, but blacks are disproportionately taking advantage of the program because they are more likely to be stuck in failing schools.  This law suit is tantamount to child abuse.  It is hard to have any respect for the politicized Holder DOJ.
