Well, the two very first FBI files state February 3rd 1974, along with a mailing location of Los Angeles (913). Even if we contend they made a mistake twice, we would then have to explain a mailing location never used before by Zodiac. The 913 attribution would also have to be explained. The mix up in dates occurred because the person who compiled a subsequent list of all the communications typed February 14th for the SLA letter, but he also typed May 6th 1974 for the Badlands letter. This person got his information from another FBI file stating
"that on 2/14/74 the enclosed letter was received by the San Francisco Chronicle". That is, received not postmarked. He just interpreted the file incorrectly. You will remember that another 1974 communication was received at the Chronicle about a month after its postmark. Here are the initial two FBI files stating 3 FEB 1974, followed by the file which was interpreted incorrectly by the compiler of subsequent lists.


Additonally, a February 3rd 1974 mailing about the SLA from Los Angeles (the day before the kidnapping), where the Symbionese Liberation Army had one of its two headquarters, makes more sense than a Zodiac Killer just reappearing after a 3-year hiatus, and by some stroke of luck, just happening to write about the Symbionese Liberation Army the day before the SLA's most noteworthy crime. Tie this with the aforementioned FEB 10 Hearst communication, signing off with "A friend" only 7 days later, and it becomes a difficult argument for the SLA letter being Zodiac. Neither the February 3rd or February 10th letters were published.
