You go Gov. Walker….
Check it out:

Wisconsin Gov. Scott Walker signed two pro-gun bills into law on Wednesday; one that removes the state’s 48-hour waiting period on handgun purchases and another which allows retired, off-duty, and out-of-state police officers to carry guns on school grounds.

The NRA-ILA weighs in on the former:

SB 35 repeals the waiting period requirement and allows a licensed firearm dealer to transfer ownership of a handgun following notice from the Wisconsin Department of Justice that the background check indicates that the purchaser is not prohibited from possessing a firearm.
