Let’s assume that you are right. Why would the pdf file have been presented as anything other than a straight scan? Why not a picture of someone in Hawaii holding it? Why not a simple press conference, TOMORROW, in Hawaii? The proper authority figure could hold up the actual piece of paper, shake it, let the press take numerous hi-def photos, which would make Arpaio, me, and all the people on here you consider birthers, look like imbeciles. Do you honestly think that Hawaiian authorities aren’t aware of the cold case posse? I’m sorry that you don’t understand how easy it is for people to locate a troll here.
The PDF is a straight scan (with OCR enabled). If they realized that it would introduce artifacts, they may have chosen another format, or they may bot have cared. The controversy helps them at this point - it just diverts a lot of time and energy from real issues.
