You'll be sad to know that Oklahoma has a D- from the Brady Center.
Of course, you can move to Washington DC where they have a 'B.' The only reason they don't have an 'A' is because Congress can repeal all of their laws. Wouldn't you feel more safe there?
Oh....Just remember, Washington DC has a murder rate of 48 per 100,000.
Oklahoma has a murder rate of 5.3 per 100,000

They don't have a similar page for D.C. I wonder why?
Just trying to help you out. Hell, I'll even drive the moving truck for you if you pay for the fuel.
