The burden of proof has shifted.

Probably every American knows the phrase "Innocent until proven guilty." In any trial, the jury must assume the defendant is innocent until the plaintiff/prosecution proves he committed the tort/crime. But that seems to have shifted with the Obama justice department.

The Justice Department has deemed Texas' voter ID law discriminatory. It says the burden is on the state to prove that it is not. Shouldn't the burden be on the Justice Department to prove that it is?
