tommy:
It identifies the boyfriend, the stranger, the criminal they have their eyes on as a person who is suspicious of committing a crime. Matching their DNA from the crime scene is absolute and cannot be wrong when it matches up.

They even have databases of DNA profiles to try to match up cases that are unsolved. It identifies plenty.

tommy:
The boyfriend kills his girlfriend, he leaves his blood behind on a knife that killed the woman. They then ask the guy for a DNA sample after he says there is no chance he killed this woman and his DNA matches perfectly. This is cut and dry, there is no explanation of why this guy would have his blood on the murder weapon other than him being the killer, and no one else could possibly have his DNA profile. End of story.

There are cases when this will not absolutely mean he killed this woman but most likely with all the other facts he did do it.

tommy:
It's not circumstantial , it's proof of being there when blood was shed when she died. Do you think he was helping her insert a tampon when she accidentally got killed?

ChadTower:

tommy seems to think you can get a 100% perfect DNA match to a specific individual that cannot match anyone else on the planet.

Do you know how complex DNA is? Do you know how rare it is for two people to anywhere near having the same DNA? Even mother and son are far from exactly matching but you can see similarities.  A complete stranger is so far off the map even you can tell the difference.

When you match up one guys DNA with the same DNA it's unmistakable.
