Booth's visit to the Surratt Boarding House after the assassination

[J. Beckert]

Why use a revolver if you have both and the smaller Deringer worked? And if the Deringer didn't work, he'd have the revolver. I just don't buy the idea that Booth trusted this small window of opportunity to a one shot pistol. It makes no sense to me. If you carry a gun and need to use it, you should really carry two - just in case.
