1) the Nazi's set up a "public friendly" concentration camp in the Czech Republic, Theresienstadt (1), which they took officials from the Red Cross to and used in media reports sent to the West which demonstrated the "rich Jewish cultural life." of their camps.
2) Crazy Eddie, an electronics store in the early 1980's which turned out to be a massive investor fraud, (2) had a warehouse filled with boxes so he could have an audit, a necessity to go public - the first row of boxes were filled with merchandise, the rest of the boxes were empty.
TL;DR - Humans are trusting people, show them something, and tell them "everything else is just like this thing", and most people will believe you at your word.
