"Spy & Counterspy"

I came across a resource that I thought I would share. It is a site called "Spy & Counterspy" which has a collection of articles on recognizing and neutralizing surveillance, particularly focusing on techniques of those organizations that can roll out large scale surveillance against a subject.

     If you find the articles useful, there is a link that allows you to download a .zip file of all of the articles as well as a couple well-known books on the basics of lockpicking.

     This information seems to pair well with the series of articles on "Dark Arts for the Good Guy" at Matthew Allen's blog.
