No one on the live thread knew for sure what had happened.
For those who didn’t see it.
The camera zeroed in on the judge, who was against the railing and a set of stairs. Off the corner of the screen, you saw a woman with a sign flash by, followed by a superfast security, with another woman with a sign following, then a group of security.
You heard a thud (they obviously grabbed them just as they were going over the rail or close to it) and a small scream of rage or hurt. They pulled them back and hauled them back up the steps, the the crowd started booing them big time.
The announcer ignored it. But you did hear a faint yelling in the background as they were hauled off.
