Interesting physical security government resources

Most of us deal with network and information security on a daily basis. At times, it can be both edifying and also daunting to read about what those on the front lines of physical security deal with.

Two of my favorites are the FBI list of concealed and hidden weapons, and the the DEA's Microgram Bulletin which lists concealed drugs - an interesting read for security analysts. Cocaine in hammock supports, other drugs in trailer hitches, and more.
