who is going to have a rearguard’s responsibility to handle antifa when they show up?
That's a good question. I know that when I went to a rally a couple of years ago (in Kentucky), the local police and plenty of SS agents were there. I have to wonder if some of the outside crowd wasn't armed as well, being in eastern semi-rural Kentucky. You weren't going to get in with any weapon, not even a pocket knife, but outside, not sure how well-policed that was concerning firearms.
That venue was a sports arena at a local college in the area. held maybe 9000 people.
