Largely. The Courant says the following:
There were no boos from the crowd for either Lieberman and Lamont Monday, and supporters for each cheered lustily as their candidate passed. There was a minor scuffle between a Lieberman supporter and a Lamont backer and police were called in, but no charges were filed. (AP)
However, some blog sources say that the incident got a bit ugly:
The ugliest moment came when during this same press conference one of the Liebergoons attacked a man holding a Lamont sign while the same man was holding an infant child probably no older than six months. The Liebergoons ripped up part of the Lamont sign. Liebergoons attacked another man holding up a Lamont sign during the same conference. I can accurately report, having witnessed these events, that several of Lieberman's goons initiated physical contact with Lamont supporters but NO Lamont supporter did that to a Lieberman supporter.
Joe was standing there and the cameras were rolling when Joe's goons attacked two Lamont supporters. Had Joe any decency he would have told his staffers to knock it off but JOe continued on in his press conference.
No way to verify just how accurate this report is. Can anyone who was there verify?
But it seems to have passed pretty peacefully, otherwise.
