"Mob scene" is Meade's expression. He was there, unable to get in and hearing rumors about legislators unable to get in.
MORE: From Meade: Legislators can get into the building, but Republicans are being blocked from getting to their offices and into the Assembly chamber. It's the Assembly that needs to vote on the bill that the Senate passed last night, leading to the renewed protests. Meade heard from a source that Democratic legislators unlocked at least one door that leads to the doors for a cluster of Republican legislative offices. That would appear to be part of a scheme to prevent the vote. [ADDED: The door was unlocked to let the area filled up with protesters and block the office doors.]
"This is what democracy looks like" — that's the chant we've heard for 3 weeks. How do you like this new democracy, that has a mob storming the Capitol and, with the aid of the minority party, blocking the access of the majority party into their offices and into the legislative chamber? It looks more like anarchy to me.
