No, the scientists behind DNA testing absolutely understand the limitations.

The people who don't understand the limitations of science and possible errors in certain methods are clueless jurors and the cops who pay a random person $800 to sit on the stand, say they are "and expert" and claim there's a trillion to one odds that two people could have "the same" DNA, even though that isn't even remotely what was tested!

Courts allow basically anything as long as you can pay a guy to say they are an expert and parrot whatever you want. But somehow that's treated as if it's the fault of biologists and others who do DNA analysis?

Maybe our courts shouldn't be based on "Trust anything a cop says, period"

That has not always been the case. They were dead wrong about the population size needed to produce false positives for the number of sites usually compared in the 1990s. These were _scientists_.

Thinking that scientists have always known the limitations kind of proves my point about even most highly educated people not understanding science.
