1974 is the real year for several of 1969 Zodiac publicized letters. The Belli Letter is not 1969. Identifying everything on the envelopes, the stenographic code and/or anagramming the notes....well anagramming reveals things happening in 1974. Nixon is going to quit the game, Patty is kidnapped and brainwashed, Watergate and the burglars and Mark Felt, future true crime cases are talked about, Lightning Amen, KKK.....and more is seen via just decoding the communications.
