More Liberal Civility

My question is how did the union thugs and goons get on the floor of the Assembly?
from jsonline: Democrats erupted after the vote, throwing papers and what appeared to be a drink in the air. They denounced the move to cut off debate, questioning for the second time in the night whether the proper procedure had been followed.
"Shame! Shame! Shame!" Democrats shouted in the faces of Republicans as the GOP lawmakers quietly filed off the floor and a police officer stood between opposing lawmakers.
"Cowards all! You're all cowards," yelled Rep. Brett Hulsey (D-Madison) as another Democrat tried to calm him down.
Most Republicans had no comment on the vote afterward and some were escorted out under police protection. Earlier in the night, Majority Leader Scott Suder (R-Abbotsford) said that Democrats had been given more than two full days and nights to make their case - effectively turning the debate into a filibuster - and that Republicans had done nothing wrong.

If there is any doubt that the Assembly Democrats and their supporters are union goons and thugs, I think that doubt has been dispelled.
