Okay
i must not have been clear in my original post
My problem is the police departments are not working together.
SFPD DNA is non existent ! the envelope was tested on the outside which dozens of people touched before it went into evidence.
Riverside has not worked with the other departments due to them being locked in on a suspect.
When was the last time all 4 departments had detectives meet up and present and share all evidence with each other ? The 70’s ?
Are the separate police departments clearing suspects and not sharing that info with each other.
Zodiac is not brilliant he’s lucky that jurisdiction and politics have prevented this case from being solved.

That’s what I thought too, but you need to read Tahoe’s post here.
