Palin won't cooperate with investigation on "Troopergate"

Poor Governor Palin, perhaps she should read her history books regarding Richard Nixon and Watergate. She would then know that sometimes it is the coverup which is much worse than the original misdeed. Here is the latest link: http://www.msnbc.msn.com/id/26727937

If the governor has nothing to hide, won't the truth come out if she cooperates? This looks suspiciously like an attempt to stonewall until after election day in November. Didn't the Republican legislature in Alaska commission this investigation? What makes the investigation "tainted"? Inquiring minds would like to know.
