Two examples of the government classifying information for (what seems to be) no good reason.

1. They are re-classifying old previously unclassified documents. Some of the documents being re-classified don't contain any apparant state secrets and are very old (documents relating to the Korean War, for example).
2. They are classifying death certificates. Even acquiring a close relative's record seems like it will now be very difficult.

What's that Jello Biafra line sampled in the Ice-T song...
"In reality, what they are really trying to do is control access to information itself."

"...and if they can't do it by law, there are other ways they can do it."

although, the law obstacle really isn't what it used to be, it seems.
