Putting a press release on a website where it doesn't belong has been done; it's old news. We know you can hack a drupal site owned by the .gov, we get it. Don't blow your wad on something obvious, get documentation that would make Woodward and Bernstein cream their pants over how many pageviews it'd get and publish that.
Hack the FBI and find out who was talking about killing protestors at Occupy Houston; hack Corrections Corporation of America and find out what they talk about during their board meetings; get their financials and spill them to the foreign press. Any or all of those would change things, possibly for the better. But this, this is a waste of your time and ours.
