she showed up to make a statement
"Oh boy, I'd better go show solidarity with New York." so, by her own admission, she was there for a purpose... as such, while not condoning the actions of the authorities, was apparently caught up in the situation and who knows this might have been a staged foto event. (no there wouldn't have been that opportunity would there?)
however, reminds me of the bloke, who several years ago, during a protest, tried to block a train going into or out of a military facility and he laid down on the tracks in front of engine. imagine his suprise when the train couldn 't stop in time and due to his own stuborness didn't move off the tracks and the engine rolled over him and amputated both of his legs above the knees...he complained of mistreatment and everyone (his fellow protesters, judical, etc.) stated he was dumb enough to lay down in front of a moving train he should accept and endure his action(s).
bottom line, if u 'show up' to demonstrations, accept the fact you might get sucked into something you can't control and then be responsible enough to accept your accountability of your actions.
