This statistic can be developed only by review ef individual casesx in those matters mat likely to have been targets of electronic surveillance. This would entail review of literally hundreds of case files at FBI Headquarters. In many cases, this Yeadquarter's file review would not indicate Whether entry | or trespass vas effected in the conduct of a survey. It would be necessary in a number of cases; therefore, to review. field office files {and in some cases to interview personnel) to learn which cases fit into the above category. With respect to Title III surveillances, no — pre-court order surveys have been conducted in relation to microphone installations. Where microphones have been installed, the initial entries were not conducted util issuance of a court order. If the microphone installation was subsequently determined to be not feasible, the installation was not made. . : Enclosures (8) NOTE : This memo im res nds to to questions ‘posed < by AAG, Civil Rights Division, in his letter of 12/2/75 (copy attached to yellow) and incorporates information | furnished the INTD by Laboratory Division (memorandum ' J, Cochran, Jr., to Mr. Wannall, 12/11/75), Special — Investigative Division (memorandum R.
