So where was security in that section. That went on for sometime and had the potential of escalating into violence. Some or all of these idiots should have been tossed out.
For singing? It looked like it was all in good fun but a bit rude though. Also if security went in and tried to throw them out that would just escalate things more. If they started hitting them however then I could see them taken out. But from this view you probably wouldn't have even noticed it. This stuff happens at lots of games though you should see what some of the B.C. lions fans say to other people who cheer for other teams. It makes this video nothing compared to what I have seen and heard.

I can only think that the security guards either got a laugh out of it, or thought the two were part of the group and it was "all in good natured fun".
Maybe they were not there at all or never saw what happened?

Would not have happened on my watch. If I had heard that my guards stood by and did nothing. I would have wanted to know why.
You try to control and monitor every incident in a crowd of thousands. But I would agree with you on one thing if I saw this happening I would have stopped it.
