There are many, many examples of DNA testing being unreliable because of HOW it is done (for example: https://www.theatlantic.com/magazine/archive/2016/06/a-reasonable-doubt/480747/ https://www.theatlantic.com/magazine/archive/2016/06/a-reaso... ) and yet the general public still sees it as infallible.

The standards from a scientific standpoint are truly deplorable.
