I think that is a pretty accurate viewpoint.
By the way, I've been researching a "Harper's Ferry" like outbreak in Calhoun County, Florida on the eve of the war in 1860. It resulted in the calling out of the state militia.
There was heavy Alabama involvement in the episode and the "insurrectionists" were defended by Judge Yelverton of Elba, who was a delegate to the Alabama Secession Convention.
