Interesting subject. It is human nature to not want to be watched all the time. And cameras have become so prevalent, that nearly everyone has one.
The police know that violence, which for them is sometimes necessary, isn't always well received by the viewing crowd.
In your post, this was written: "police shouldn’t expect any privacy when they are carrying out their duties in public."
Police are trained to take complete control of any situation that gets out of hand and violates public law. Being human, they could add a little more violence than is necessary. That is the part that most citizens don't like.
When we are in the public arena, we can expect to be filmed, whether we be police or private citizens. With cameras and filming today, the person doing the photo taking, doesn't have to be close to us. So expect your photo to be taken while in public. Cameras are everywhere. Even stationary ones.
So, I give a thumps up on photo taking of police. Why not? We all are in the pictures. Ha
