The first use of DNA in a criminal case only goes back to 1987. As such 30 years ago people generally weren’t really aware of generic testing or any of it’s implications outside of science fiction.
I am talking about DNA wrt crimes... it was first proposed as possible in 85 and in the early 90s used for it. I'd say my timeline was fairly ok give or take a few years for an off the cuff recollection of events.
