Gathering of Eagles? I have seen them in action over the last few years. They are keen to jump on old people. But face to face, they aren't much. No thought at all.

They often fly Confederate flags, and wear bumper stickers on proclaiming that they would have been on the losing side in the Civil War.

They are mostly at events to try to provoke a response so that their friends on duty, other cops, can then arrest the people they were attacking.

Don't take the bait. Best to just show up in much larger numbers and keep your distance with lots of people taking film footage and legal observers so you can protest yourselves from the charge that you attacked them and beat them up.
