You forgot Alar and the dreaded MEDFLY that was going to eat all the fruits to extinction or something like that.
And I remember getting lectured by a cop in grade 2 or so (this would have been very early seventies), but I think he was just there to let us know about Officer Friendly, and how we should "look for a cop" if we were alone and in trouble. I don't think they were walking a beat any more even by that time. I do recall he passed around a bullet for us to examine, and I don't recall him advising us to wash our hands of the lead after. Naughty. Oh, and maybe he had some Elmer the Safety Elephant crap, too.
I think they were already pushing the "cigarettes are bad" thing, though, as I also vaguely recall getting my ass whipped for dropping a pack of smokes in the can.
