State Department advises that Commiseion

request to declassify

Legal Attache Mexico City's 5-18 "Secret" Summary

nemorandum is not

likely to cause harmful repercússions 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.

п)

The Commission on 9-22 asked us to declassify the "Secret"

181-page 5-18-64 summary prepared by Legal Attache Messico City.

The principal reason for classification of the summary

was to avoid

disclosure of

active investigation in Mexico by Bureau parsonnel, a

factor the Mexicans strongly opposed and to protect highiy sensitive

security informants Mex 18 and 19w peevided some of the data B19

in the document.

Because of possible internati.nal repercussions

between Mexico and U. S. if the summary was made

public, ve on 9-23

sought the views of the State Department.

State's 9-29. witten reply

expresses view that declassification is not likely to cause harmful

repercussions between Mexico

U.S. and, accordingly, it interposes

и)

no objection to declassification.

Legal Attache,

Mexico City, is opposed to declassification

of 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 disting

between Mexican sources and Bureau Agents.

The summary can readily be

be accomplished by deleting reference to three items which are not

touched upon in the Commission's report and by reusiting an introduction

source abroad (Legat)., The Commission's report on page 304 records

that". . . the Government of Mexico initiated a thorough investigation

to uncover as much information as possible on Oswald's trip.

Mexican law enforcement authorities."
