National Security Investigations and Prosecutions (Westlaw)Provides the law governing investigations conducted by the US government to acquire information about foreign threats to national security. National security law is often inaccessible, and can be particularly hard to follow when divorced from the context of historical tradition, governmental structures, and operational reality in which it functions. This treatise explores the full background of NSIs, both from a pre-911 and a post-911 perspective, providing a powerful tool for any attorney handling a case involving a national security investigation or prosecution.
