I believe this part: So What?? They could have talked / yelled at her all the way through the line. She had no business walking back to where they were. People can talk smack all day long. You can ignore it, talk back or call a CM in to call security. Walking back to confront them ( and I think throwing the first punch ), took the whole thing from a verbal confrontation to a physical one. was from you and it ended up in your quote of me.
Basically, you are saying that girl#1 shoulders the entire responsibility for the incident. She should have walked away. She should have ignored everything. And because she didn't, you believe she threw the first punch; even though you can't tell from that video if she actually did or not. And the fact that charges haven't been issued (at this time) confirms that she instigated it.
I just don't see what you are seeing from what was on that video.
