Well, before everything went on the internet it was much harder to find published opinions and laws as they happened. In the 90s when the guy was a child he probably only had exposure to historical documents, not current ones. I actually don’t know where you would have found the full text of those pre internet. The public library? I also found it kind of novel to read current court opinions not too long ago. Government function stuff seems like the kind of thing you learn about as a kid and don’t really update actively.
Nah, I grew up in the 80s and 90s and you could learn a lot from newspapers, magazines, television, or a trip to the library where you could get plenty more. There's no excuse for believing the stuff was secret. Not easy to get, sure, a trip downtown, maybe, but "secret from the press" for example, that's ridiculous for anyone that's ever turned on the nightly news channel in the 70s, 80s, or 90s where I have actual pre-internet experience. Also, by the early 90s you could get it all on the actual internet, pre-web, by going to a library with an internet connection and gopher. Bills, rulings, regulations, and other government publications could be found and accessed through Gopher directories maintained by government agencies, legislative bodies, and other organizations. Being away from all of this is OK if you at least know that it does in fact exist and other people use it. But believing that it doesn't exist, that government works in secret, that's just a busted education right there.
