Here’s what the Youtube description says:
“This is video from the gallery of the WI Assembly past 1 AM in the morning on 2/25/2011. The Democrats have just been told by the speaker pro tempore there will be no more debate before the vote, even though there were more than a dozen Democrats in the queue to speak. They shout “Shame! Shame! Shame!”
The public citizens in the gallery were shortly told to leave by police. None of the public were allowed in the gallery at the time of the vote.”
