Richmond councilman films latest meeting disruption
A meeting of the Richmond City Council came to a halt Tuesday night when protesters interrupted the session and began yelling, prompting police to clear the chambers.
No arrests were made during the incident, the latest in a series of interruptions at council meetings, said Councilman Tom Butt, who filmed the protesters and posted the footage on his Facebook page.
The series of videos show a group of people standing up and singing, as well as a man yelling loudly through a bullhorn.
At one point, the man, while pacing up and down the gallery, says, “You’re supposed to work for the community. A community is a group of people living in the same area, abiding by the same rules. But those who are making the rules are not abiding by them.”
The man yelled angrily, “Wait a minute!” as officers escorted him and other protesters out and cleared the chambers.
Those in the audience were forced to watch the proceedings from a television screen in a lobby.
Butt said he was at a loss as to why the disruptions were occurring.
“It appears to be an expansion of something we’ve been seeing for months and months,” Butt said. “It just goes on and on, and there doesn’t seem to be any point to it other than just trying to see how much disruption they can cause.”
