I am interested in your thoughts being distributed for discussion in the Weekly Detail, but I can't find your contact information anywhere. Please e-mail me at your earliest convenience. Thanks!

Terry, I very much like your answer to me and am going to copy it and use it! I believe that not using them at all, while an easier choice, does not contribute to our individualization process. Thanks for responding. meh

I knew if I just allowed myself a few more gray (grey) hairs, someone would respond. Thank-you indeed !
I've always looked at the fax transmitted fingerprint as simply a fingerprint with distortion. In this case the distortion is applied through the electronic processes of the machine(s) itself. If we stick to our methodology, I believe we can use the FAX, within limitations, of course.
As you know, some fingerprints reproduce reasonably well on the FAX. That is to say, features at Level 2 on the original, appear in the correct relative location on the FAX. Because our CLARITY has been compromised to some degree, our TOLERANCE for discrepancy of some features is broadened accordingly. If I can then satisfy myself that sufficient agreement exists between the questioned impression(s) and the FAX'd knowns - within tolerance - why not make the ident and seek verification?
It all boils down to reliability in the image and a sufficient volume of available information.
I always prefer to have the comparison prints enlarged to 150 or 200 %, before FAXing, which deals with the pixellation (?) problem quite well.
These comparisons are not the ideal, but are sometimes necessary in the interest of expediency. Due caution should be utilized in any case, followed by a hard-copy mailing. TS

Having just read T. A. Smith's question about fax comparisons (Sept. 2002) under the problem idents section, I was curious about what standards are used for fax comparisons. I know of agencies which will not do them at all and others (like ours) which judge on a case by case basis. What is the consensus of opinion (or is there one?) on fax transmittals?
