This is exactly the wrong way to do DNA testing. These tests have a finite accuracy (say 99.99%), so when you shotgun it across a database of tens of millions of people, you get a long list of almost all innocent people, at least one of whom may be placeable at the scene, especially 20 years later. Most defense attorneys can’t teach statistics well enough to most juries for them to understand this math.

Lot of innocent people in the next few years are going to go to jail or death row. I can only pray I’m not one of them.

Did you actually read the article? The looked up in a database for the initial hint, then followed up by matching his DNA (taken from a piece of chewed gum) to DNA found at the crime scene.
