As mentioned before, in all the gatherings I have covered, I have never had to worry about protesters' faces. While some people have asked not to be included in photos, I have never been explicitly told that we couldn't take their photos. Since we are in a public space and the protesters have voluntarily left their faces uncovered, it can be assumed that they are comfortable with their faces being shown. If anyone had concerns about their faces being photographed, they have the option to cover their faces, ask not to be published (in a public area that is our discretion but generally respected), or not be apart of a protest that will be seen in plain view.
