layout scene drawing

For the first scene  I want to establish that the law enforcement were the dominant characters of the scene. I want to use low angle shots to show their sense of scale. For the second scene I want to establish  the control over the civilians that the law enforcement have, and influenced by the German concentration camp research, were the prisoners walked along fenced paths, I will have the civilians doing the same while being watched by the law enforcement . To show all the characters I wanted to create a large scale scene. Scene three will show the dominance over the civilians they have, and will be the part just before the law enforcement attack them. This scene will also show the civilian cowering.
