You are absolutely right on the Taney arrest thing. Hummel found a previously unpublicized document on this from an official who The Lincoln had supposedly instructed to carry out the arrest. It's author appeared to be present when the warrant was discussed. Lincoln cultists responded by trying to discredit it on the grounds that no other collaborating document survives from other persons involved. They made their case to that end after Hummell's book was published but neglected one key fact. The arrest warrant is corroborated by Taney himself and eyewitnesses to his courtroom at the same time Hummel's document tells of the happenings on The Lincoln's side. Taney confided his awareness of a plan to arrest him over his Merryman ruling to other judicial officials in Maryland, and one wrote at the time of having discussed the plot specifically with Taney after hearing of it himself and urging Taney to flee the region of Baltimore for his own safety.
So when the Wlat brigade shows up to deny the fact that their false god tried to arrest the Chief Justice over a court ruling he did not like, direct them to Taney himself.
