Very much worth watching:

Zodiac starts around 16:00, but BTK, Son of Sam are before him.
Just AFTER the Zodiac segment, watch the "Abbotsford Killer" (17:20) segment. He copied Zodiac somewhat–he calls the cops boasting he did it and comments about not being dumb enough to leave fingerprints. He writes on a headstone…"she is not the first and she won’t be the last".
They play the ACTUAL calls. "I’ll be cruising around"…
Too young to be Zodiac, but "story" is interesting! Father was a cop, 30 yrs. old, no criminal history. Sent off to school while siblings got to stay home. He too wanted to be a cop, but was rejected….starts his own "patrol" on his police radio.
“…they may be dealing with one or more ersatz Zodiacs–other psychotics eager to get into the act, or perhaps even other murderers eager to lay their crimes at the real Zodiac’s doorstep.“ L.A. Times, 1969

Sounds interesting, will watch later. I think I must have either read or watched something about this recently because the "starting his own patrol" bit sounds really familiar and I bet I’ve already watched this lol. Just noticed it’s the most evil series and I’ve been watching those over the last few nights. 
Still I completely missed the bit you quoted above.
