It's just as boring and ignored as it was six years ago. While most of the stuff is useful for consideration very little of it would make any difference. That is to say, much of the info about what happened was left out of the public publication, and most of the suggestions for future prevention are negligible to useless.
Yeah, I had to read it. There is a lot of information in it, but they were required to keep out countless other info that was classified, damaging to public officials, or damaging to investigations. Also, what's done is done and reading about it doesn't change it. The recommendations would help, but once you implement a stricter form of security, or organization, and so on there is only a very very short period for which it's effective before it's compromised. Where there's a will, there's a way.
Yup, studying history has never helped anybody. We might as well give up on improving the system because no matter what, because there's a will, the is definitely a way... guess we'll just wait for the next attack.
