Not surprisingly you have this wrong. Arrest them on what charge? Talking about rebellion? Advocating rebellion? Supporting rebellion? The envoys were not the leaders of the criminal ring, just the flunkies. Tossing them in jail would have done nothing to alleviate the situation.
Your words. Then you turn around and say that envoys from an illegally established (accoridng to you) CSA government are not breaking any laws? It appears as though Mr. Lincoln is not the only one acting incongruently on the subject.

HAHAHAHAHAHAHAHAHAHAHAHAHa
Mr Lincoln arrested men on all these "charges" throughout the war.
Tossing them in jail would have done nothing to alleviate the situation.
Tossing them in jail would have put his buns in a political sling from which there was no escape.
