A few days, ago, I wrote this post exploring a 1945 memo from TJAG Myron Cramer regarding various legal issues surrounding the program that evolved into Operation Shamrock (as well as various other, more-conventional, collection activities). At the time I didn't feel free to provide a PDF of the memo itself, since I'd gotten it through the (for-pay) ProQuest database.

Historical Context for Today's Surveillance Debates: The 1945 Legal Memo on What Became Operation Shamrock
Section 702 is coming up for renewal later this year, and it is clear we'll be hearing a lot in that context about the impact of SIGINT collection activities on US person communications. When that topic comes up, inevitably there follows at least a brief reference to the Church Committee's exposure of Operation SHAMROCK and Operation MINARET. In light of all this—or perhaps just because I love archival finds—I'm writing this post to capture some 1940s history that helps us better understand those 1970s revelations—and how if at all they pertain to today's controversies.
