The leaked government documents from Wikileaks show the possibilities that the hikers could have been brought to the Iranian border and arrested.
According to the Star Tribune, the 400,000 page document was written when the hikers were detained July 31, 2009. The origin of the documents are being questioned even though they look authentic. The Pentagon has declined to say if the documents are authentic or not.
As mentioned on CNN.com, the document "has been heavily redacted". It also ends with an assessment that reads, "the lack of coordination on the part of these hikers, particularly after being forewarned, indicates an intent to agitate and create publicity regarding international policies on [Iran]".
