bficken,
I think an easy presentation, that anyone of any experience and background is interested in, is a presentation that says: here is what our agency does. Here is our policy. AND when we use this policy we get results % time. When we switched to procedure B, we got results % time.
What I think should be shared are more interagency details like:
% latent recovery: porous, non-porous, what techniques are you using? Which are most effective in what type of cases?
% IDs? % Inc? % Exc?
More often IDs to Suspects? Victims/Elimination? More often prompted suspect? or AFIS hits?
How often do you have differences of opinion for examiners? How do you resolve?
etc.
Unfortunately, many agencies are very stingey about providing this info. I think it's a shame. I'd like to see some of the larger, more influential labs, SHARING this info, rather than guarding it so closely. In this way for example, I see Alice Maceo's LVMPD lab as a leader for sharing their policies and effectivness. I also was very impressed with San Diego's SD's presentation last CDIAI conference on inconclusive AFIS results. I think these presentations are easy to put together, easy data to collect, and I wish more people would publish these data. Klasseys/ATF's gun paper on latent recovery is still a staple paper years later and all they talked about was recovery of latents with one technique from guns! So simple, yet so important.
In another thread Tazman and Boyd discuss the pros and cons of reviewing the AFIS candidate list by a verifier/verifying exclusions. But while both make good points...where are the data? How much extra time was spent? How many were caught? What type of cases? How many people/man hours? How many extra cases did one lab get out (and how many more idents were made in a timely fashion, but at the sacrifice of some erroneous exclusions) and so on. The discussions would have some great value if one or the other could show the cost and benefit to the two procedures.
So my suggestion is collect some data for the next 6 months. And then share those results.
These are data ANY agency can collect and share.
