The National Rifle Association says it hopes a restaurant shooting in Oklahoma City in which the alleged shooter was shot dead by two armed citizens serves as a "wake-up call" for the state's Republican governor.

The NRA said in a tweet Friday that the Thursday shootings were an example of "how the best way to stop a bad guy with a gun is a good guy with a gun."

The NRA has been critical of Oklahoma Gov. Mary Fallin for vetoing a so-called constitutional carry bill that would have allowed adults to carry firearms without a license or training.

The Oklahoma City Police Department said two armed citizens shot and killed the alleged gunman after he emerged from a restaurant where at least three people were injured by gunfire.

Fallin released a statement Friday afternoon in response to the NRA's statement:

I am thankful that under the concealed-carry and open-carry laws that I have signed as governor, two armed citizens had the ability to protect and save the lives of our fellow Oklahomans. This is not the time to debate the NRA’s efforts to repeal Oklahoma’s regulations assuring safety and training for those who carry guns. This is a time to offer up prayers to the victims of this tragedy.
