"Bussed in" as in being given bus tickets for scheduled bus lines, or as in charter buses paid for by Soros and company? The armed "Oath Keepers" who showed up to protect a favored blogger/journalist should be meeting those buses, silently taking photos and videos of the contents. That would result in an attack or two from the troublemakers and maybe derail their plans before they could get into place to cause real harm.
I honestly do not know which kind of “bussed in” my friend meant.
However, if the 2012 Presidential elections in my corner of South Florida are any indication, it would be the Soros Variety. I saw it with my own eyes here.
