Baltimore mayor Stephanie Rawlings-Blake told the press that her city "gave those who wished to destroy space to do that" at last night's protest. Watch here:
"I 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 try to make sure that they were protected from the cars and other things that were going on, we also 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 de-escalate."
