"You won't shoot, Barney, because since I knew I might meet you and you'd pull a gun, I had myself searched by two friends just before I came up here.

They'll testify I was not armed.

They know you, and know you so well that they'll be able to identify the thing in your hand as your gun.

So no matter what Maggie and Jimmie may testify, the verdict will be cold-blooded murder and the electric chair will be your finish.

And that's why I know you won't shoot.
