The problem was that many could not hear the PA system. They did announce the presence of ProtestWarrior, explained that you needed to read their signs carefully and that they are on our side. But many folks could not hear that. The crowd that was not under the tent was "churning" all the time, moving to the front, moving back to the sides or back of the tent (there was a large open area between the tent and the stage. The incident occurred near the front of the tent, where the sound system could be heard, at least when men were talking, and talking in to the mike. But I'm sure it could not be heard farther back. Even people sitting around me did, who should have heard the announcement, since my muzzle blast diminished ears did, still didn't catch it nor understand what the protest warriors were/are about.
FReepologies to the Protest Warriors.
lol ~ my husband said he heard it - but I didn't and I was sitting right next to him!
