DEAR ROY COHN: This little missive is for your waste paper basket or your conscience, whichever comes first.

       You wouldn't know me but I have followed your
career with abiding interest way back to the Army-McCarthy time, because I was Executive Editor of The Post and you had a habit of turning up in news stories.

       I know it is none of my business but I rise now on the subject of the Moonies and Roy Cohn.

       Your parents were Jewish (mine too).

       The clear and irrefutable anti-Semitism of the Rev. Moon's movement is all on the record and easily checked by a man with your resources and investigative talents.

       This is just to say that I am shocked that you would take money from such a tainted source. Nobody--no Jew, surely--can possibly need it that badly.

       End of unsolicited sermon.
