Wisconsin | Unfortunately nobody on the case understood basic statistics. If you have somebody who's a one in 100,000 match for your suspect, but you searched a population of 100,000,000, then there's 1,000 matches in that population. The same danger was rampant in the early days of DNA when testing wasn't as fine grained. Even now, DNA has to be a screening tool, it's relatively weak on it's own. For example, a DNA match to a John Doe is compared to the persons age, weight, height, and if they went missing at the time the body was found. Old crime scene DNA is compared to whether the suspect lived in the area, knew the victim, etc. Fargo PD completely blew this one, if we're getting the whole story. | |
