Typically, in that situation the cops would just escort them off the premises after they started dancing, and cite park regulations.

If they persisted, then would write ticket them with a fine.

I am no fan of Code Pink, but they won that PR battle. They would have had nothing to "show" had the cops escorted them off, then fined them, then arrested them.

The cops overstepped their authority, and acted like people who were over-reacting because they do not like Code Pink message. The cops fell into their trap, so I cant really say that I approve of their actions.
