...while, all along the top of the picture, there are dozens of people with cameras taking pictures of what his colleagues are doing, and probably hundreds of those images were somewhere on the web before the arrest was over.
This is what the people who are giving these orders have failed to grasp: you can no longer hide your approach to 'crowd control,' because everyone in that crowd will have a camera and many of those cameras have the capability to immediately disseminate the images. Used to be you could grab the cameras and pull the film out. In today's modern world, by the time you've grabbed the cameras, the images are out there on the Web already.
Guns, night sticks, pepper spray, mace, and so on are pretty fearsome when you confront them in the actual situation. As far as what happens around about and *after* the actual situation, the cameras matter a lot more. Along with all the other things this picture represents, it is a picture of a whole lot of FAIL.
