Extreme Copyright – Why is there Copyright on FOIA issued Documents?

It’s sad to see yet another child star go down in the dumps. Recently, Amanda Bynes, the teenage hottie on Nickelodeon’s All That, and The Amanda Show, from the late 1990s into the early 2000s, got charged for a hit and run, and another unrelated charge recently as well.
The E! network had posted a PDF of the Freedom of Information Act or FOIA request of her charges. E! has recently upgraded to a new content management system or CMS to gather all their stories, posts and other web pages such as programming to easily manage. This went live just as the network rebranded themselves as “The culture of Pop” (which I think is retarded if you asked me.) This change happened in early August, and Broadcasting & Cable had done a writeup explaining this multi platform website layout was supposed to have copyright protection. I can understand that, but…
Since they posted the PDF of a FOIA issued document, E could not help themselves of putting their huge logo as a watermark on, again, a public record document that is supposed to be copyright exempt.
Here is the document directly from the network’s website.

I have nothing against protecting intellectual property, but when it gets out of control, I do have something against it – especially when it was made by the government of California and not produced by E themselves (maybe feeding it into their copier/scanner but still that can’t be copyrighted due to FOIA protection.
