Here is an interesting way that the Illinois version of the Brown Act was enforced. The County Board was subject to citizens’ arrest, followed by the sheriff taking the entire board into custody except the one supervisor who did not vote. Theoretically, this could happen in Richmond.

Two Veterans Perform Citizens Arrest on Entire County Board, They Laugh Until Sheriff Shows Up
By Reagan Wilson on November 22, 2014      
Many times, normal people get frustrated and wonder what they could possibly do to fight an out of control government. This could happen at the local, state or national level.
Fortunately, at the local level, this is often entirely possible. Two military veterans in Illinois recently placed an entire county board under citizen’s arrest after they violated a state law. The board basically laughed it off and told the pair to sit down and shut up.
They weren’t very amused when the local sheriff showed up though. According to The Ocala Post:
In what was one of their most epic displays of political crime-fighting, which was captured on video, Allen and Kraft held the entire Clark County Park District Board under citizen’s arrest on May 13, 2014, for violating the Illinois Open Meetings Act, a Class C misdemeanor.
When asked if there would be public comment, one of the board members said, “I vote no.” Followed by five other board members.
Board attorney, Kate Yargus, could be heard on video saying there would be no public comment that night, and told the board members they were “free to go,” even after Kraft’s citizen’s arrest announcement. She tried to cite statute to Kraft, but before she could finish, he said, “Just sit down, you are making yourself look like a fool.”
When the sheriff showed up he did in fact arrest 6 out of the 7 board members. One of the board members had voted against the other 6 and was not arrested.
