Total misunderstanding, CedarDave. Their signs got them into trouble, because if people read them quickly, they seemed to be saying some bad things.
I think by the time it was all sorted out, everyone was happy again.
I certainly knew who they were, and I was yelling something like "They're the good guys, leave them alone!", but my shouts just added to the din. Syncro above explains more about what happened.
They certainly are to be congratulated for their initiative leading to tonight's victory.
