JUSTICE will be done more often: a new method of fingerprint analysis could not only detect prints but also reveal when they were made. Techniques for capturing a fingerprint are farfrom perfect. Besides the well-known method of dusting, there are several more sophisticated ways of detecting fingerprints, but all have limitations. Software analysis and chemical agents can often enhance a fingerprint, but can sometimes muddle the pattern instead. And while atomic force microscopy can pick up fingerprint residues precisely, the technique scans such a small area at a time that it can often take hours to assemble a single print.
