There was a nutcase gunman. It was all on video.
Now, unless someone has a theory that the nutcase gunman was really an android, or that there was a “grassy knoll” in this, one is left with just the nutcase, politically motivated as he may be.
He was mad about something no doubt. On FR also most people seem to be mad about something. But only rarely is there such a motivated nutcase.
And operating ON HIS OWN? I doubt it.
There was also an attempted coup in Hungary. This guy was as much a useful idiot as “nutcase”. The evil pricks behind all this mean business. You can bet Trump is their #1 focus.
