Branigan 1 — Rosen 1 + Malley 1 — Branigan LEE HARVEY OSWALD - $tokes INTERNAL SECURITY - RUSSIA ~ CUBA State Department advises that Commission request to declassify Legal Attache Mexico City's 5-18 “Secret” summary memorandum is not likely to cause harmful repercussions between Mexico and U. S. and it has no objection to declassification. This recommends that we prepare a sanitized unclassified version of the summary for delivery to the Commission, a procedure which the Commission now states will meet its needs. The Commission on 9-22 asked us to declassify the "Secret" 1Sl<page 518-64 gummary prepared by Legal Attache Mexico City. The principal reason for classification of the summary was: to avoid disclosure of active investigation in Mexico by Bureau personnel, a factor the Mexicans strongly opposed and to protect highly sensitive security informants (Mex 18 and 19) who provided some of the data in the document. Because of possible international repercussions between Mexico and U. 8. if the summary was made public, we on 9-23 sought the views of the State Department. State's 9-29 written reply expresses view that declassification is not likely to cause harmful repercussions between Mexico and U. S. and, accordingly, it interposes no objection to declassification. Legal Attache, ‘Mexico City, is opposed to declassification ef the document in its present form and suggests that, if possible, a sanitized version be prepared by deleting three nonsubstantive items which are not referred to in the Commission's report and by deleting references to sources of information through which reader may distinguish between Mexican sources and Bureau Agents. r On 10-1 Miss Hennigan, secretary to W. David Slawson, stafi member of the Commission, advised that uublic disclosure of the summary in its present form is in any/ ectionable to the Bureau, & redraft.of same deleting or changing the material which may be harmful to Bureau's operations would fully fit the Commission's needs providing the rewrite covers all of the Mexican aspects of this investigation touched upon by the Commission report. 105-82555 JCS: pdb (10) Nos —— eo xy ye ree Docld: 32319372 Page 2?
