Hampe reading (s?)

Hampe Questions:

1) Hampe says 'editing is at the heart of documentary.' Since editing is obvious done post-shooting, how does this separation take away from a actual depiction of reality? Or could this editing enhance it?

2) How does one find the confidence in a documentarian to trust what they are showing as a tru documentary? What can one do to instill this trust into his audience, or is this purely a gut feeling or something based on reputation, as popular documentarians are today?

3) What difficulties do you feel you will encounter with the video project between what you intend to shoot, and what you actually shoot and can use to edit? How does this differ from the audio project
