There are several issues going on in one post. Number one, what is the officer's definition of a "point". I have heard some non-expert officers refer to the delta and the core as "points" in a pattern. Most officers or detectives understand the word "point" to mean a bifurcation or ridge ending. But latent print examiners use other fine detail in two impressions as landmarks or "points" on which an identification decision can be based. As such, the definition is the first thing that must be nailed down.
Also, some experts may tell you they don't "count points" when an examination is conducted. They are simply saying that there may be other information present, and to just say a number of points would not completely represent the examination. The only true way to make progress toward a determination that the examiner or officer was incorrect is for another qualified expert to conduct another examination.

Yes, i would like to know too. My stepson was charged on a case because the police said they have two points of a print, the police officer didnt even know how many points there even were.Can they do that?

There are approximately 75 to 150 friction ridge details on the first joint of a finger. On a palmprint the average is
250 to 350* over 2,000 friction ridge details.

Does anyone know how many minutiae points (ridge endings and bifurcations) there are in each fingerprint. I know the number of points required for a match is low, but how many is there on a print?
