Someone did a live feed of the group. I watched it. Of note, nobody said anything except a couple leaders who were ordering the reporter to stop filming - there was no indication WHY they were marching.
The Black Panthers did this cr@p back in 1969 on the UC-Berkeley campus - toting rifles and shotguns, with the cops watching them like hawks. Nothing new under the sun.
The guns were empty; the Panthers weren’t THAT stupid.
