Sounds a lot like how liberal sh*thole states are dealing with efforts to curb illegal immigration and masked ANTIFA violence.
In many instances the same areas.....and this comes from the spawn of the same people.
What Texas (and others) complained of is what we would now call "state sponsored terrorism." The big shock from John Brown's raid was:
A) they were carrying Sharps rifles which were the newest and best...and were very expensive. No rag tag bunch of poor terrorists could possibly have afforded those and everybody knew it instantly.
B) when several prominent New Englanders openly admitted that they had put up the money/sponsored the terrorist attack, their states refused to prosecute them or extradite them.
Just imagine if after 9/11 a bunch of prominent Saudis had publicly announced that they sponsored the terrorist attack and the Saudi government then refused to prosecute them for it or hand them over. What would the American people have thought? What would they have demanded? How would the US Government have reacted to that?
It was the same then......the same realization many of us have had about Leftists in the last decade. ie These are not merely people I disagree with or my political opponents. These people genuinely want us dead. They are actual enemies. That's how most Southerners felt after that. They were given damn good reason to feel that way.
