Except as the article lays out, Lincoln did sign the order and several people knew about it - including Taney himself.
In whole numbers. If a country with a population of 30 million arrests 50,000 people while a country with a population of 5 million arrests on 25,000 people then in which country do you have a greater chance of being arrested. I'll give you a hint, the second one.
I've produced a source saying upwards of 38,000 arrested by Lincoln without charge or trial. I produced another source - a PC Revisionist at that - who says Davis arrested far fewer people and suspended habeas corpus far less. In support of your claim to the contrary you've provided.....Mark Neely. LOL!
Except that none of Taney's biographers, including Taney himself, ever mentioned it.
