What Is the Difference Between a Revolver and a Semi-Automatic?

There were no shell casings like Brett just mentioned found at the restaurant. An expert did testify that the ammunition found at Stokes home would fit a revolver but not a semi-automatic. Jackson said that he had a cold automatic so that confirms what Wells testified to the type of gun that Jackson had and he said that Stokes was the one who had a revolver. And this all makes a lot of sense because remember it's Jackson who's driving the car."
