Perhaps I am foolish to think so, but the prospect of a Civil War is not out of the question as far as I'm concerned. Not armies of thousands fighting battles all over the country, but rather assassinations and guerilla raids here and there against the opposition. Politicians, justices and judges, media personalities, etc., could be targets for attacks. Maybe certain locations too; state, regional, or national HQ buildings and or media outlets or central broadcast or internet sites could also be targeted. Maybe even people, businesses, and places could be attacked for their political affiliation or connection.
Could we see future attacks on the FoxNews building in NYC or the CNN building in Atlanta or wherever it is. Maybe there would be an attack against the pillow guy's business in Minnesota, or some other business that is staunchly political one way or the other. Is it not possible that a politician or justice/judge or media personality could be attacked at home or elsewhere for their political stance?
I do not see this as likely any time soon, but I wouldn't rule it out either.
