I find it interesting that, in support of your disapproval of the gate crashers, you used a photocopy of a manual which has as its first full paragraph:
"Note: It is a violation of Federal law to duplicate or reproduce this manual without permission. It is not to be photocopied or released to anyone outside of the Executive Office of the President, White House Military Office or United States Secret Service. It has been developed for your guidance and is intended for your personal use....
SENSITIVE - DO NOT COPY"
Even if this wasn't your personal Manual, pasting the link here would also be a federal offense, would it not? I don't know how it's done now, but we had to turn ours in for shredding.
