The emotional and chaotic scene irked both Republican and Democratic lawmakers, while others pointed out that although signs were banned, the public could still freely carry firearms inside the legislative office building. Signs were present during a House committee hearing Wednesday morning.
I bet if they brought signs reading, “2nd amendment >1st amendment,” they’d be allowed to stay.
