referring to myself.  If you consider some material exempt from diclosure,release the material to me with deletions indicated 
and specify your legal support for having made those deletions.  Finally, Irequire a response within ten working days, as 
provided by theFreedom of Information Act.  I appreciate your time and your compliance with my request and the law.                                        Thank you,                                        <YOUR NAME>This letter must be notarized.  To notarize a letter go to somebank, NOT the Post Office.  The bank will check youridentification a stamp your letter, then go to the PO and mailthis letter.  The C.I.A. also has files, but I believe they stoppedupdating information in 81.
