Visible crew/equipment: When Preston's apartment is being searched, he walks into his bathroom to find his hidden Prozium capsules. He shuts the door in the camera's face and when you see the interior of the bathroom (with the camera behind Preston) you can very briefly see the cameraman's head. (01:28:05)
Visible crew/equipment: When Preston returns to the Equilibrium after he has uncovered his window, there is a shot where the camera slowly moves from the front of the crowd to the back of the crowd. If you look at the backs of the people to the right you can see a shadow moving from someone in the film crew. (00:32:55)
Visible crew/equipment: When Brandt picks up Preston from Equilibrium you can see the white screen in the reflection of the front passenger window. (00:24:35)
Visible crew/equipment: After verifying that the Mona Lisa found is the real thing, the guy with glasses turns his head to Preston. As he does, a white screen is reflected in his glasses. (00:06:50)
Chosen answer: As I see it, the point of the speeches is not to evoke emotions in the listeners, but rather to show what emotions such as anger and jealousy lead to in the course of human history. So they use historic "evidence" to justify their actions (such as killing sense offenders) and to show what emotions can lead to.
