2017 is the copyright of the book. Not the origin of what happened in 1865. I realize they may not have copyrights in coloring books and thus your ignorance of them. But, keep your Crayola's handy. History books have notes and endnotes where they cite their sources from.
For example: The quotes given on p.(129) one is based on 'Congressional Globe, 39th Cong., 1st sess., December 14, 1865, 50'. Another is based on 'Congressional Globe, 39th Cong., 1st sess. December 14, 1865, 108'. Do you disagree with these quotes? If so, why? And please support your answer.
The quote given on p.(136) is based on 'Congressional Globe, 39th Cong., 2d sess., December 12, 1866, 86-90'. Do you disagree with this quote? If so, why. And please support your answer.
Concerning the quote on p. (137), do you disagree with the authors statement that due to Congress's inquiry into the Davis case, that Attorney General Speed issued his official opinion of the Davis case in January 1866?
Concerning the quote on pages (137-138), do you disagree that that was Attorney General Speed's official opinion? If so, please present what it really was. And show from where you got it.
In other words, your 2017 remark is just another of your shit statements. Point being, the Jeff Davis trial would be held in a real court of law, and not a military lynching tribunal. And that caused the damnyankees to shit all over themselves knowing they would be found guilty of treason.
