Yes, it was a dumb thing to say. Her press rep clarified her remarks with this statement:
"What she is saying within this statement was that there was an effort to give the peaceful demonstrators room to conduct their peaceful protests on Saturday. Unfortunately, as a result of providing the peaceful demonstrators with the space to share their message, that also meant that those seeking to incite violence also had the space to operate. The police sought to balance the rights of the peaceful demonstrators against the need to step in against those who were seeking to create violence.
The mayor is not saying that she asked police to give space to people who sought to create violence. Any suggestion otherwise would be a misinterpretation of her statement.”
This was her full quote with emphasis and "as a result" added by the author of this article to demonstrate what she says was her intention:
“I’ve made it very clear that I work with the police and instructed them to do everything that they could to make sure that the protesters were able to exercise their right to free speech. It’s a very delicate balancing act, because, while we tried to make sure that they were protected from the cars and the other things that were going on, we also [as a result] gave those who wished to destroy space to do that as well. And we worked very hard to keep that balance and to put ourselves in the best position to deescalate, and that’s what you saw.”
Whether you accept that explanation or not, it probably was a stupid way to phrase it, I give you that. And, for the record, of course I don't support violence or looting. But, whatever the truth on the mayor's statement, it's interesting that in this whole story, that is what you're choosing to focus on and start a thread about. It's rather Breibart'esque.
