I assume that you accept that Booth assassinated Lincoln? Apply your standard of proof used in the JFK case to the Lincoln assassination so that we can understand the difference with Oswald. Link Booth to the weapon for example. Where are the prints, pictures, documents, serial numbers, and witness testimony that link Booth to this specific pistol? Where did he obtain it from? Where did he buy his ammo? Prove to us that Booth even carried that pistol or any pistol into Ford's Theatre. What witness, for example, saw him carry it into the theater? Show us a chain of custody regarding the pistol found or even who found it in "situ" (a word kooks love). There are various and conflicting reports of who, when, and where it was found. Prove to us that pistol was even used to kill Lincoln. The bullet recovered from Lincoln can't be matched to that particular gun. Show us how Booth loaded it since no such tools necessary to load the Derringer could ever be associated with him. Don't cop out and tell us anyone saw Booth shoot Lincoln. That would contradict the standard you apply to the JFK case. They just heard what they "assumed" to be a shot like a loud "bang" and looked in that direction to see someone that looked like Booth pointing some unknown object at Lincoln. No one saw him actually pull the trigger (i.e. the pedantic interpretation of seeing someone shoot another person such as in the Tippit murder). Maybe it was a pipe or something else "made of wood" in his hand. Like the object Marina and Bob Jackson described believing it to be a rifle but which you dismiss as being something else. Maybe Booth just pointed it at Lincoln and shouted "bang" and someone else actually fired the shot from another location. Explain to us why Booth would have carried only a single shot pistol. It all just sounds like "opinions" and "assumptions" applying your form of logic because it is an impossible standard of proof.
