She was the antagonist, attempting to make her way to the front of a Rand Paul rally, hold up her fake support sign, and make the natural supporters behind her unwitting accomplices in an anti-Paul photo op. Without her actions, none of this would have happened. She is not an innocent victim in this event.
But what did she do that actually warrants an apology? I can understand that her actions would have led members of the crowd to physically prevent her from moving up to Paul, and apparently they were acting out of serious concerns for Paul's safety. I therefore disagree with those who suggest that anyone in the crowd but the stomper did something wrong, at least as far as I can tell. But moving forward in a crowd doesn't need an apology. Trying to do a dumb political stunt doesn't need an apology. Getting pictures in a crowd doesn't need an apology. Generally being a dumb liberal activist doesn't need an apology. So what's her apology going to read? "I'm sorry other people misinterpreted my intention"?
