I have, have you?
I have studied the Texas Declaration of Secession, look at how many times they mention slavery...
Get a copy of Editors Make War: Southern Newspapers in the Secession Crisis by Donald Reynolds. It has a whole chapter in it describing how Texans handled that period of "Servile Insurrection". Won't be the first time mob violence was effectively used in Texas.
Do you know of any of the men that signed the Ordinance of Secession?
